There are a number of problems:
1. Since I am using a PPC7455 based computer 64bit executables won't run and the 64 bit libraries are effectively cross compilations. So the configure scripts need the same APPLE LOCAL mods used in libstdc++ to avoid testing in the configure script whether the compiler can build executables. (with the -m64 flag the executables are built but they won't run).
Would love to see mainline enhanced to keep track of issues like this. Hard problem, few people willing to conquer it. If you want to do up patches for our branch, I'd entertain putting them in.
2. libgfortran.h line 63 defines int8_t.
Ick! Sounds like the configure mechanism went haywire. stdint.h should be found and included, and that, should define HAVE_STDINT_H and that should cause it to not be defined. I wonder if you might have to have a G5 build system for the configure hair to work as it is. The config.log might say more.
Anyway, if you want it to just work, I suspect you'll need to either pick fortran or -m64.
