Oh, sorry.
It was a part of source from rawstudio which used to work correctly but since

Also, I don't think the change you're seeing can be from GCC, since
unconditionally does #undef __USE_GNU
Did you upgrade glibc at the same time as gcc?
In any case, you should use the documented interface, not __USE_

You're not supposed to define __USE_GNU yourself, see
The macro you should define is _GNU_SOURCE, which causes glibc to define
__USE_GNU

The strange thing is that when I copy the problematic part (even with
__USE_GNU) to a different file it works.
