Modified files:
	cm3/m3-libs/m3core/src/thread/PTHREAD/: ThreadPThreadC.c 

Log message:
	Use __thread on Linux and Solaris.
	Doesn't compile on Apple.
	Segfaults on OpenBSD and NetBSD.
	Not tested on FreeBSD, AIX, Irix, HP-UX, etc., stick with pthread_get/setspecific.
	In future hope to eliminate this code anyway, in favor of gcc/libgcc stack walker
	or C++ exceptions (C++ backend).
