plug-ins/common/bz2.c plug-ins/common/gz.c plug-ins/common/mail.c 

2000-11-08  Michael Natterer  <mitch@gimp.org>

	* plug-ins/common/bz2.c
	* plug-ins/common/gz.c
	* plug-ins/common/mail.c
	* plug-ins/common/screenshot.c
	* plug-ins/common/url.c: applied a (modified) version of
	gimp-quinet-20001108-1.patch which adds proper checking of the
	return value of waitpid(). Removed the lines adding
	gimp_signal_private() because of the fix below.

	* libgimp/gimp.c: Don't install a SIGCHLD signal handler but simply
	call gimp_signal_private(SIGCHLD, SIG_DFL, SA_RESTART) instead.

	This is IMHO the right thing to do because the reason for the
	introducion of the signal handler was the SA_RESTART feature
	and not the handler itself.
