--- Comment #7 from Marc Glisse <glisse at gcc dot gnu.org> 2012-09-30 14:19:20 UTC --- (In reply to comment #5) > include/c++/4.8.0/cmath for darwin Dominique, it would be more useful if you could show your libstdc++ config.log, and in particular the error message you got for the test "for ISO C99 support to TR1 in <math.h>", to know what functions are missing on darwin (or hppa or others), assuming there isn't already a PR somewhere about it.
