Hello,
I have cross-compiled binutils (2.18) in an environment, where though
glibc headers are used, but _GNU_SOURCE is undefined in features.h
immediately after it defines _XOPEN_SOURCE/_POSIX_SOURCE and the others
(the target library does not provide any of the GNU extensions either) and
found that binutils does not need any of the GNU extensions (meaning those
guarded by __USE_GNU), haven't tracked down which are enough of all those
defines, but _XOPEN_SOURCE and/or _POSIX_SOURCE could be more appropiate
to reflect the reality.
Peter

Binutils is written portably. It isn't supposed to and does not
require _GNU_SOURCE. But it does detect some GNU extensions in
configure and use them if they are available (e.g. stpcpy).
