This change is only useful for the conformance tests since the headers changed are not installed. The conformance tests fail due to IS_IN not being defined, so wrap it with a check to make sure that _ISOMAC is defined. * include/bits/stdlib-float.h: Use IS_IN only if _ISOMAC is defined. * include/mqueue.h: Likewise. * include/stdlib.h: Likewise.
