--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Jobst.Ziebell from comment #4) > Presumably this bug also occurs when #defining the other '__need_*' macros. Which user code should never be doing anyway. GMP is broken (and already fixed upstream). This is documented at http://gcc.gnu.org/gcc-4.9/porting_to.html and isn't going to be changed to accomodate broken libraries.
