* cygrun.c (main): Fix compiler warning.

* gmon.c (_mcleanup): Ditto.
* profil.c (profile_off): Ditto.
* net.cc (find_winsock_errno): New function.
(__set_winsock_errno): Use find_winsock_errno.
(cygwin_setsockopt): Detect SO_ERROR for debugging.
(cygwin_getsockopt): Ditto.  Translate error when getsockopt returns SO_ERROR.
* winsup.h: regparmize __set_winsock_errno.
* include/sys/strace.h: Document that strace functions can't use regparm.
