of functions (car, cdr etc.) from the dsubr family of functions
(i. e. functions that take a double precision floating point
argument). Further, the algorithm for handling the cxr function
is improved.

(scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
(scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
typecode for the dsubr family of functions.
* ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
ramap_dsubr.
* eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
(scm_init_pairs): Make use of the (now usable) second cell element
of a scm_tc7_cxr function to implement the cxr family of functions
more efficiently.
of HAVE_LONG_LONGS with "SCM_SIZEOF_LONG_LONG != 0". Replace
usage of ptrdiff_t with scm_t_ptrdiff. Replace usage of
SIZEOF_PTRDIFF_T with SCM_SIZEOF_SCM_T_PTRDIFF.
with the versions in this module using
scm_c_extend_primitive_generic.
* goops.scm (equal?): Define default method.
* goops.c (scm_primitive_generic_generic): Enable primitive
generic if not enabled.
(scm_sys_goops_loaded): Setup unextended primitive generics.
* goops.c, goops.h (scm_c_extend_primitive_generic): New function.
* snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
snarf macros.
* numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
testing example. All uses of SCM_GPROC should be converted.)
* procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
scm_assoc.
* eq.c (scm_equal_p): Turned into a primitive generic.
with any following code (for GCC 3 strict-aliasing).
* numbers.c (scm_make_real), num2float.i.c (FLOAT2NUM): removed
the earlier version of the reordering prevention.
* *.c: add space after commas everywhere.
* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
Document cases where SCM_WRITABLE_VELTS() is used.
* vectors.h (SCM_VELTS): prepare for write barrier, and let
SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.
* autogen.sh (mscripts): find and check version number of
autoconf. Complain if 2.53 is not found.

scm_logxor, scm_i_dbl2big), srcprop.c (scm_source_properties,
scm_set_source_properties_x, scm_source_property): Removed
compile time option SCM_RECKLESS to clean up the code. Full
number of arguments checking of closures is mandatory now.
However, the option to disable the checking has most probably not
been used anyway.
* srcprop.c (scm_source_properties, scm_set_source_properties_x,
scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
(mem2complex): Do not create negative NaNs.
(scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
NaN.
(scm_inexact_to_exact): Signal error when converting a NaN.
* numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
and scm_nan.
* numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
[SCO && ! HAVE_ISINF] (isinf): New function.
(xisinf, xisnan): New functions.
(IS_INF): Delete.
(isfinite): Define in terms of xisinf.
(scm_inf_p, scm_nan_p): New functions.
(guile_Inf, guile_NaN): New file-scope vars.
(guile_ieee_init): New function.
(scm_inf, scm_nan): New functions.
(idbl2str): Handle Inf and NaN. Remove funny label and
corresponding gotos.
(ALLOW_DIVIDE_BY_ZERO): New macro.
(scm_divide): Allow division by zero to occur if
ALLOW_DIVIDE_BY_ZERO is defined.
Handle bignums and ints as special cases.
Additional stuff by me:
numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
(scm_even_p, scm_odd_p): Treat infinity as even and odd.
(iflo2str): Don't output a '+' for negative numbers or for Inf and
NaN. They will provide their own sign.
(scm_divide): Only allow divides by inexact zeros. Dividing by
exact zeros still signals an errors.
non-zero is returned from a port or smob free function.

appropriate. Return zero from smob and port free functions.
* debug-malloc.c (scm_malloc_reregister): Handle "old == NULL".
* fports.c (scm_setvbuf): Reset read buffer to saved values when
it is pointing to the putback buffer.
* win32-socket.c (getservent, setservent, endservent,
getprotoent, setprotoent, endprotoent): New functions.
Appropriate replacements for M$-Windows.
* numbers.c (SIZE_MAX, PTRDIFF_MAX, PTRDIFF_MIN): Reintroduced
these definitions for GUILE_DEBUG.
* net_db.c: Include "win32-socket.h" if compiling with a native
M$-Windows compiler. Include some pieces of code (protoent and
servent interface) protected by HAVE_* macros when using a
native M$-Windows compiler.
num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
now rely on SIZEOF_ macros that have been figured out at
configure time.
* num2integral.i.c: Adapt to new interface.
(NUM2INTEGRAL): Test whether a fixnum can be represented in the
target type by casting it and checking whether it is still the
same. Do not try to handle bignums for integral types that are
smaller than fixnums. When handling bignums, collect the
magnituse first into a unsigned type, and correctly check for
overflow.
(INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
only -MIN_VALUE can still be negative of all negative numbers (in
twos-complement).
* configure.in: Include `win32-socket.o' in the list of object
files if networking is enabled on Win32.
2001-11-07 Stefan Jahn <stefan@lkcc.org>
* win32-socket.[ch]: New files. Defines Winsock-API error codes
and makes them available through Guile. That is because the
Winsock-API does not store its errors in `errno' and thus cannot
return error messages via `strerror (errno)'.
* socket.c (scm_init_socket): Initialize `win32-socket' part
here under M$-Windows.
* numbers.h: Added missing declaration of
`scm_sys_check_number_conversions()'.
* error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
and use in `(strerror)' and `(system-error)'.
* Makefile.am (EXTRA_libguile_la_SOURCES): Added
`win32-socket.[ch]' to extra source and header files.
* NEWS: Corrected remarks about SCM_API.
* configure.in: Defining USE_DLL_IMPORT definition to indicate
usage of DLL import macros in `libguile/__scm.h'.
(LIBOBJS): Removed `fileblocks.o' from the list of object files.
Somehow Jim Blandy's patch from 1997 did not survive.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* configure.in (EXTRA_DEFS): Follow-up patch. Using SCM_IMPORT
instead of __SCM_IMPORT__.
* readline.c (scm_readline_init_ports): Disable input/output
stream redirection for Win32. The readline package for Win32
does not support this. The guile-readline library works fine
for command line editing.
* readline.h (SCM_RL_API): Renamed __FOO__ macros into FOO.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
here (was at guile_LDADD) which describes the dependency
correctly and allows a clean build on Win32.
* __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
into FOO.
* __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
import macros for external libraries (libcrypt, libqthreads,
libreadline and libregex).
* coop-defs.h: Include <winsock2.h> for `struct timeval'.
* posix.c (flock): Added support for flock() in M$-Windows.
* guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
of __SCM_IMPORT__.
* fports.c (getflags): Differentiate reading and writing pipes
descriptors.
* filesys.c (S_IS*): Redefine all of the S_IS*() macros for
M$-Windows.
* coop.c (coop_condition_variable_timed_wait_mutex): Use
conditionalized error code if `ETIMEDOUT' is not available.
(scm_thread_usleep): Remove bogus declaration of `struct timeval
timeout'.
* numbers.c (PTRDIFF_MIN): Moved this definition where it actually
belongs. That is because NO_PREPRO_MAGIC gets undefined after
each inclusion of `num2integral.i.c'.
(SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* md/Makefile.am (EXTRA_DIST): Added `i386.asm'.
* md/i386.asm: New file. Contains the Intel syntax version for
nasm/tasm/masm of the file `i386.s'.
* qt.h.in: Definition of QT_API, QT_IMPORT and QT_EXPORT.
Prefixed each symbols which is meant to go into a DLL.
* Makefile.am (libqthreads_la_LDFLAGS): Put `-no-undefined'
into LDFLAGS to support linkers which do not allow unresolved
symbols inside shared libraries.
(EXTRA_DIST): Add `libqthreads.def', which is an export file
definition for M$-Windows. It defines exported symbols. This is
necessary because the M$VC linker does not know how to export
assembler symbols into a DLL.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* srfi-13.h, srfi-14.h, srfi-4.h: Follow-up patch. Renamed
__FOO__ macros into FOO.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* tests/ports.test: Run (close-port) before (delete-file) if
necessary/advisory.
across a hexdigit after having read a # or if not reading a hex
value. This will enable the calling code to correctly handle
forms like 1e2. (The background is, that the exponent markers d,
e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
providing this patch.
(mem2complex): Fix erroneous double-negation. Now, numbers like
1-i will be read correctly.
* num2float.i.c: New file, multiply included by numbers.c, used
to "templatize" the float <-> num conversion routines.
* numbers.c: New functions: scm_num2float, scm_float2num,
scm_num2double, scm_double2num.
