* hashtab.h: Bugfix: use SCM_API (WAS: extern).

* socket.c: Remove obsolete comment about socklen_t.
(s_scm_setsockopt)[!HAVE_IP_MREQ]: Do not use ip_mreq code.

* numbers.h (isnan)[__MINGW32__]: Remove.

* Makefile.am (gen_scmconfig_SOURCES): Bugfix: Add
DEFAULT_INCLUDES when cross compiling.

* threads.c (ETIMEDOUT, pipe)[__MINGW32__]: Add defines.

* stime.c (s_scm_strftime)[!HAVE_TM_ZONE]: Use
SCM_SIMPLE_VECTOR_REF instead of SCM_VELTS.  (Changed slightly
from Jan's patch.)
