--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- Are you playing "use as many configure options as possible"? Most of those options are on by default anyway, others don't do anything. I'm pretty sure --enable-libstdcxx-time is redundant on darwin. --enable-multiarch is for Debian Where did you get that command, and if it's causing so much trouble why not try simplifying it?
