non-zero is returned from a port or smob free function.

vectors.c, weaks.c: Use scm_gc_malloc/scm_malloc and
scm_gc_free/free instead of scm_must_malloc and scm_must_free, as
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.
(SCM_SYMBOL_INTERNED_P): New.
* symbols.c (scm_symbol_hash): Use scm_ulong2num instead of
SCM_MAKINUM since hash values can well be bignums.
(scm_mem2symbol): Only use hash values below SCM_T_BITS_MAX/2.
This signals a interned symbol.
(scm_mem2uninterned_symbol, scm_symbol_interned_p,
scm_make_symbol): New.
* convert.c, convert.h, convert.i.c: New files containing C
array to Scheme conversion helpers meant to be replacement
functions for the deprecated gh interface.
* Makefile.am: Setup rules for new `convert.*' files.
2002-01-31 Stefan Jahn <stefan@lkcc.org>
* configure.in: Add -DLIBLTDL_DLL_IMPORT to INCLTDL when using
`libltdl.dll'.
* configure.in (guile_cv_have_uint32_t): Look also in
`stdint.h' for uint32_t.
2002-01-28 Stefan Jahn <stefan@lkcc.org>
* symbols.c (scm_c_symbol2str): New function, replacement for
`gh_scm2newsymbol()'.
* strings.c (scm_c_substring2str): New function. Proper
replacement for `gh_get_substr()'.
* socket.c: Include `stdint.h' if available for the `uint32_t'
declaration.
* scmsigs.c (s_scm_sigaction): Initialize `chandler' (inhibits
compiler warning).
* backtrace.c: Include `lang.h' for GUILE_DEBUG conditional.
comments.
(scm_deval_args, deval_args): Renamed scm_deval_args to
deval_args, since it is not part of the interface.
(SCM_CEVAL): Added (maybe somewhat verbose) comment. Avoid to
use references to debug.vect[0] before it exists. Add parentheses
to switch statement.
* goops.h: Added local emacs variables.
* srcprop.c (scm_source_property): Remove redundant SCM_IMP
test.
* strings.c (scm_c_string2str): Clarified comment. Replaced
THINKME by FIXME for uniformness. Removed question about whether
arguments need to be protected from garbage collection: Arguments
must be protected as any other variable.
* strings.c (scm_c_string2str): New function. Converts a
given Scheme string into a C string. Also put in two
THINKME's regarding the malloc policy for the missing converter
routines.
SCM_GC_SET_CELL_WORD, SCM_GC_SET_CELL_OBJECT): New macros.
(SCM_GC_CELL_TYPE, SCM_CELL_WORD, SCM_CELL_OBJECT,
SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT, SCM_FREE_CELL_CDR,
SCM_GC_SET_CELL_OBJECT): Express in terms of SCM_GC_CELL_*
macros.
(SCM_FREE_CELL_P): Express in terms of SCM_GC_CELL_TYPE.
* inline.h (scm_alloc_cell, scm_alloc_double_cell): Use
SCM_GC_CELL_* macros when accessing free cells.
