I'm not sure that I did something wrong, since it's working under cygwin64 with the same config options. Also I'm building gcc since version 3; more or less the same way. Also "make" worked, just "make install" gave the undefined references which leads me to believe there's a bug in bootstrapping. $ gcc -v Using built-in specs.
