------- Comment #31 from iains at gcc dot gnu dot org 2010-05-29 07:47 ------- 4.5-branch (as of r160013) has an error in config.gcc (which I just fixed on trunk yesterday, with r159979) in which several t-make fragments are included twice on x86_64-*-darwin*. I wonder if this could be the origin of the problem?
If anyone is interested to try it out I could make you a patch for 4.5-branch to do the same fix. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43170
