Description tbsaunde 2014-10-12 19:54:43 UTC 
If for whatever reason you miss the requirement that you need a c++ compiler to build the first error you hit is
checking for uintmax_t... yes
checking for uintptr_t... yes
checking for int64_t underlying type... long long
configure: error: error verifying int64_t uses long long
Makefile:4042: recipe for target 'configure-stage1-gcc' failed
make[2]: *** [configure-stage1-gcc] Error 1
make[2]: Leaving directory '/src/gcc-opt'
Makefile:21799: recipe for target 'stage1-bubble' failed
make[1]: *** [stage1-bubble] Error 2

Which happens because that configure check happens to use C++.  It seems to me explicitly checking for a C++ compiler would be better.  This is reproducably by putting a dummy g++ in your path that just exits 1.
make[1]: Leaving directory '/src/gcc-opt'
