Thanks, I wasn't clear about the _ISOMAC macro usage.  Updated patch,
no change in generated code and the conformtests are fixed.

	* include/bits/stdlib-float.h: Use IS_IN only if _LIBC is
	defined.
	* include/mqueue.h: Likewise.
	* include/stdlib.h: Likewise.

The ChangeLog is obviously wrong, it should be:

	* include/bits/stdlib-float.h [_ISOMAC || !IS_IN (rtld)]:
	Include bits/stdlib-float.h.
	* include/mqueue.h: Use internal code only when _ISOMAC is not
	defined.
