Description Michael Kerrisk 2006-09-09 04:16:30 UTC 
In <sys/mman.h>, mremap() is exposed if __USE_MISC is set, that is if
_BSD_SOURCE or _SVID_SOURCE is defined.  

Since mremap() is Linux specific, this mremap() should instead depend on
_GNU_SOURCE.  Note also that in <bits/mman.h>, MREMAP_MAYMOVE and MREMAP_FIXED
are only exposed if _GNU_SOURCE is set, so that _GNU_SOURCE is in any case required.
