[patch] gcc4 fixes


This is just a trivial change of argument to execl() testcases, which
supresses the warning 'missing sentinel in function call' in gcc4 that
causes the tests to fail.

winsup/testsuite
2005-05-17  Brian Dessent  <brian@dessent.net>

	* winsup.api/signal-into-win32-api.c (main): Use 'NULL' instead
	of '0' in argument list to avoid compiler warning with gcc4.
	* winsup.api/ltp/execle01.c (main): Ditto.
	* winsup.api/ltp/execlp01.c (main): Ditto.
	* winsup.api/ltp/fcntl07.c (do_exec): Ditto.
	* winsup.api/ltp/fcntl07B.c (do_exec): Ditto.

This fixes the problem of mmap() not working with gcc4.

winsup/cygwin
2005-05-17  Brian Dessent  <brian@dessent.net>

	* mmap.cc (mmap64): Move 'granularity' into file scope so that
	it will be initialized.
