Your problem here is not the ABI variable, your problem is the fact that it can't find a working copy of GCC. Why this is I can't tell you, you'll have to check your PATH and backtrace your steps. See the attached log, on a 64-bit system it first checks whether the current compiler can compile 64-bit binaries, as I've compiled a 32-bit system the answer is no so it defaults to 32-bit. Having said that, however - on a seperate note - the use of ABI=32 should stop GMP from checking for 64-bit compatibility to begin with. I don't believe that putting ABI=32 in the CFLAGS is working, but using `ABI=32 ./configure --prefix=/usr --enable-cxx --enable-mpbsd' would serve the purpose. Can anyone else with a 64-bit system confirm this?
