* 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.

|
|

non-pair cells.
(SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
the return value is signed. Thanks to Brian Crowder for the bug
report.
(SCM_SRS): Avoid unnecessary casting and don't unpack input
values. With this patch, SCM_SRS can be safely used for other
types than scm_t_signed_bits. However, it should still better be
an internal macro and thus be renamed to SCM_I_SRS.
(SCM_MAKINUM, SCM_INUM): Use proper casting.
|
|
SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
macros. (The NUM names might soon change.)
* numbers.h: Added missing declarations.
|
|
* Some more renamings to SCM_<filename>_H.
|
|
|
|
|
|
|
