* ports.c (scm_port_for_each): new proc. implements port-for-each,
which applies a procedure to each port in the port table.
ports.h: declare scm_port_for_each.
* ioext.c (scm_dup2): new proc. implements "dup2" which is a simple
wrapper for the dup2 system call (unlike dup->fdes or
primitive-move->fdes).
* ioext.h: declare scm_dup2.
* filesys.c (scm_close_fdes): new proc. implements "close-fdes"
which is a simple wrapper for close system call (unlike scm_close).
* filesys.h: declare for scm_close_fdes.
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
"directory" to "directory stream". A predicate named "directory?"
would be confusing.
* filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
At the Scheme level, "directory?" -> "directory-stream?".
(scm_dir_print): Use the phrase "directory stream" in printed form.
* filesys.h (scm_directory_stream_p): Prototype renamed
accordingly.
* filesys.c (scm_directory_p): new procedure "directory?" Returns
a boolean indicating whether its argument is a directory
port as returned by opendir (thanks to Dirk Herrmann for the
suggestion.)
* gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
* ports.c (scm_truncate_file): renamed from scm_ftruncate.
allow the 1st argument to be a fdes or filename as well as a
port (as in the filesys.c version).

* genio.c: don't use SCM_SYSCALL when calling ptob procedures.
do it where it's needed in the port smobs.
* filesys.c (scm_input_waiting_p): moved to fports.c, stdio
buffer support removed. take SCM arg, not FILE *.
* filesys.h: prototype moved too.
* fports.c (scm_fdes_to_port): new procedure.
(local_fgetc): use read not fgetc.
(local_fclose): use close, not fclose.

* ports.c (scm_add_to_port_table): check for memory allocation error.
(scm_prinport): remove MSDOS hair.
(scm_void_port): set stream to 0 instead of SCM_BOOL_F.
(scm_close_port): don't throw errors: do it in fports.c.
avoid signed/unsigned comparison warnings, and because the return
value of readlink may be -1. Don't bother casting the third
argument to readlink.
* filesys.c (scm_dirname, scm_basename): Move these to their own
page, at the end of the file.
* filesys.h (scm_dirname, scm_basename): Add prototypes for these.
* stime.c (scm_times): new procedure.
* ioext.c (scm_fseek): if the first argument is a file descriptor
call lseek.
(scm_ftell): if the first argument is a file descriptor call lseek
(sic).
* filesys.h: prototypes for scm_open_fdes, scm_fsync.
* filesys.c (scm_chmod): if the first argument is a file descriptor,
call fchmod.
(scm_chown): if the first argument is a port or file descriptor,
call fchown.

Add DEFER/ALLOW INTS to a few other procedures.
(scm_fsync): new procedure.
(scm_open_fdes): new procedure.
(scm_open): use scm_open_fdes. If mode isn't specified, 666 will
now be used.
(scm_fcntl): the first argument can now be a file descriptor. The
third argument is now optional.
* posix.c (scm_execl, scm_execlp): make the filename argument
compulsory, since omitting it causes SEGV.
(scm_sync): return unspecified instead of #f.
(scm_execle): new procedure.
(environ_list_to_c): new procedure.
(scm_environ): use environ_list_to_c. disable interrupts.

cstime.

* ports.h: prototypes too.
* ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.

throw an error if an error other than EBADF occurs.
* filesys.h: scm_close prototype.
* filesys.c (scm_close): new procedure, can close file descriptors
and ports (scsh compatible).
* ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
optional argument.
primitives.
load errno.scm.
* netconst.scm: undefine maybe-define and maybe-define-so after use.
* errno.scm: new file.
* fports.c (scm_open_file): pass errno to scm_syserror_msg.
* filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
SCM_FD.
* filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
scm_syserror_msg.
* (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
scm_sys_dup): deleted: FD capability will be added to other
procedures.
* Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
scm_fd_free, fd_smob, scm_intern_fd.
* (scm_open): renamed from scm_sys_open. Return a port instead of
an FD object. Make the mode argument optional.
* (scm_sys_create): deleted, it's just a special case of open.
(scm_init_filesys): move interning of constants O_CREAT etc.,
here (were previously using SCM_CONST_LONG macro).
Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
don't newsmob fd.

include "fports.h" and <stdio.h>
(scm_stat, scm_select): don't support FD objects.
* error.h: adjust scm_syserror_msg prototype.
* error.c (scm_syserror_msg): take an extra argument for errno.
Using the global value didn't always work, since it could be
reset by procedure calls in the message or args arguments.
* fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
I don't understand why the check was there (and what about the
ultrix check?)
* strop.c (scm_string_copy): allow shared substrings to be copied.
* unif.h: corresponding change to prototypes.
* unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
recognize two new optional arguments: offset and length. Allow
the port argument to be an integer (file descriptor, for scsh).
Include <unistd.h> for "read" prototype.
Motivation: This is system specific code which is related to file
I/O. It also may use select. Added code by Gary Houston to
detect presence of character in stdio buffers.
File is now empty; deleted.
* files.h: Deleted.
* filesys.c: scm_sys_delete_file is now here. Remove
#if's; they seem to rely on remnants of an old portability
regimen. If the problems come up again, solve them properly,
using autoconf. Specifically: Don't test M_SYSV, and #define
remove to be unlink if it's #defined; don't use remove just
because HAVE_STDC_HEADERS is #defined.
* filesys.h: Add declarations for scm_sys_delete_file.
* Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
files.o, files.h, files.c, and files.x.
* init.c: Don't #include "files.h", and don't call scm_init_files.
main #include path; put most of them in a subdirectory called
'libguile'. This avoids naming conflicts between Guile header
files and system header files (of which there were a few).
* Makefile.in (pkgincludedir): Deleted.
(innerincludedir): New variable; this and $(includedir) are enough.
(INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
(installed_h_files): Divide this up. Now this variable lists
those header files which should go into $(includedir) (i.e. appear
directly in the #include path), and ...
(inner_h_files): ... this new variable says which files appear in
a subdirectory, and are referred to as <libguile/mumble.h>.
(h_files): List them both.
(install): Create innerincludedir, not pkgincludedir. Put
the installed_h_files and inner_h_files in their proper places.
(uninstall): Corresponding changes.
