So where is the autoconf 2.64 from the config.og coming from? autoconf is run by a gcc developer. It is not run when compiling gcc. This is not an issue. > I can send the whole config.log if that will help, but here's the bottom-most bits of it: This is probably the wrong config.log file. You need the one in the directory in which configure is being run. In this case, gcc/config.log. In general, the bottommost parts of config.log are not helpful. You need to look for the failing test.
