--- Comment #41 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-09-06 14:17:18 UTC --- Ah, actually not completely, the #if defined __i386__ || defined __x86_64__ && defined _GLIBCXX_X86_RDRAND line in your patch is wrong, there should be () like in the other two preprocessor conditionals. --- Comment #42 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-09-06 14:20:15 UTC --- Sorry if I'm saying something naive - I didn't follow the whole discussion - but I don't understand why - assuming indeed we want to do something at configure time - are being attached patches directly touching libstdc++-v3/configure* files, instead of acinclude.m4 (to be processed by autoreconf), which is the normal way we write this kind of code in the libraries.
