Subject: 	* common/filestuff.c: Check USE_WIN32API before including 
 sys/socket.h. 	(HAVE_F_GETFD): New define. 	(mark_cloexec): Check
 HAVE_F_GETFD. 	(gdb_open_cloexec): Change 'mode' to unsigned long. 
 (gdb_socketpair_cloexec): Check HAVE_SOCKETPAIR. 	(gdb_pipe_cloexec):
 Check HAVE_PIPE. 	* common/filestuff.h (gdb_open_cloexec): Change 'mode'
 to unsigned 	long.
