------- Comment #6 from redi at gcc dot gnu dot org 2010-07-06 13:03 ------- Also, I don't think the change you're seeing can be from GCC, since <features.h> 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_GNU -- redi at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44837
