Hi Volker, Yes, this was a bit confusing for me too, and yes the build-system appears to have changed a little: gcc-4.2.4 did not need gmp/mpfr/mpc gcc-4.3.x and 4.4.x need gmp/mpfr/mpc as binary libraries, won't accept the sources. gcc-4.5.x and 4.6.x need the sources, won't accept the binaries. -So I have 3 different cases in my build-script. ;)
You can probably leave the ABI=32 out entirely. I needed it only for 4.3.x and 4.4.x... :) Instead of making symbolic links, some people prefer copying the sources directly into gcc's source-directory, but making symbolic links works the same way, I have no problems anymore. =) Try it out and see if it builds.
