Browse source 
* 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.
