commit 7a9ebfa159f392fcf1c3aa172fc5bd6bd1eeea63

    Use IS_IN internally only
    
    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.
