[PATCH 3.3] fix ada/10546

[Laurent Guerby <guerby at acm dot org>]

This has been tested (boostrap + ACATS) on a Red Hat Linux 9 system 
with glibc 2.3.2 / libpthread-0.10 and under a Debian system with 
glibc 2.2.5 / libpthread-0.9, I also checked bits/pthreadtypes.h 
and they had a different pthread_cond_t definition. 

Identical ACATS results.

Ok to commit on 3.3? HEAD will take the fix from ACT
with the merge.

Thanks to Roch for providing me access to his machine.

	PR ada/10546 
	* 5iosinte.ads: Increase pthread_cond_t size to match recent
	LinuxThread and NPTL version.
