Subject: [Ada] Fix handling of signals under VxWorks

Manually tested on VxWorks, automatically tested on x86-linux
Committed on mainline.

The routine to clear the VxWorks task exception count is needed because VxWorks
longjmp performs this operation.  Not resetting the count was preventing proper
handling of multiple signals.
In addition the signal code is always executed by the "current task", so
the conditional to test and issue a taskResume was useless.

2004-12-07  Ed Falis  <falis@adacore.com>

	* s-intman-vxworks.adb (Notify_Exception): removed useless check for
	current task being suspended.

	* init.c (__gnat_clear_exception): added to reset VxWorks exception
	count.
	(__gnat_map_signal): removed test for current task being suspended.
