Subject: ftw.c affected by g++/glibc issue __USE_GNU is defined.

When compiling as C++, __USE_GNU is defined even though
we use -ansi and don't specify -D_GNU_SOURCE anywhere.
Glibc headers don't seem to respond to the C++ ANSI options.

ftw.c: Workaround for compiler warning: only define
__USE_GNU if it is not defined already.
