	-mthreads -- see the EGCS documentation.

	The library should be testing for _THREAD_SAFE macro on AIX.  I
think that it tests for _REENTRANT or something like that used by some of
the OSes.

	None of the GCC support libraries are built with -mthreads option
(and we have not yet added that to the already large number of multilib
permutations for AIX).
