>Description:
	stdio.h uses _THREAD_SAFE
	math.h & openssl/e_os.h use _REENTRANT

	On linux, _THREAD_SAFE & _REENTRANT are documented to be
	synonymous (in /usr/include/features.h).  I don't know what
	POSIX has to say on the issue (although it looks like they use
	_POSIX_THREAD_SAFE_FUNCTIONS - see comment in unistd.h).

	Of course, _REENTRANT is not mentioned in gcc(1) whereas
	_THREAD_SAFE is.

>How-To-Repeat:
	egrep -r '_REENTRANT|_THREAD_SAFE' /usr/include

>Fix:

	Until a possibly better, more posix compliant, solution comes
	along, either:
	 - Have headers use just _THREAD_SAFE or _REENTRANT
	 or
	 - Have headers use treat _THREAD_SAFE or _REENTRANT
	    the same.
