data. (dynl_smob): Use it.
* dynl.c (scm_dynamic_link): Moved allocating of the memory for
the dynamic object data below the linking of the object to avoid
memory leak when the linking code throws an error. Now the code
leaks a whole dynamically linked library when must_malloc throws,
but that should be much less likely.
* stime.c (tzset): If tzset isn't provided, make it a NOP.
(scm_localtime): Change SCM_EOF to SCM_EOL.
(scm_mktime): Likewise.
* socket.c: Don't include sys/un.h unless autoconf tells
us Unix domain sockets are available.
(scm_fill_sockaddr): Ignore Unix domain code.
(scm_addr_vector): Likewise.
(scm_init_addr_buffer): Likewise.
(scm_socketpair): Don't include unless socketpair was
found during autoconf.
* simpos.c (SYSTNAME): Treat cygwin like Unix.
* scmsigs.c (scm_pause): Don't include unless pause was found
during autoconf.
* posix.c (scm_getgroups): Don't include unless support function
was found during autoconf (in this case, getgroups).
(scm_setpwent): For setpwent.
(scm_setegid): For setegid.
* net_db.c (scm_inet_netof): Don't include unless support
function was found during autoconf (in this case, inet_netof).
(scm_lnaof): For inet_lnaof.
(scm_inet_makeaddr): For inet_makeaddr.
(scm_getnet): For getnetent, getnetbyname, getnetbyaddr.
(scm_getproto): For getprotoent.
(scm_getserv): For getservent.
(scm_sethost): For sethostent, endhostent.
(scm_setnet): For setnetent, endnetent.
(scm_setproto): For setprotoent, endprotoent.
(scm_setserv): For setservent, endservent.
* scmconfig.h.in: Regenerated.
* configure.in: When sys/un.h exists, define HAVE_UNIX_DOMAIN_SOCKETS
to indicate that Unix domain sockets will work.
Check for socketpair, getgroups, setwent, pause, and tzset
(cygwin currently lacks these them).
Check for sethostent endhostent getnetent setnetent endnetent
getprotoent endprotoent getservent endservent getnetbyaddr
getnetbyname inet_lnaof inet_makeaddr inet_netof (cygwin currently
lacks them). In the case of cygwin, temporarily prefix these
functions with "cygwin32_", the way that netdb.h does.
Don't define HAVE_REGCOMP unless both regcomp and regex.h are
available (cygwin b18 came distributed without a working regex.h
file).
* acconfig.h (HAVE_UNIX_DOMAIN_SOCKETS): Add this.
* configure: Regenerated.
