The companion C processor is gcc. It is generating
prototypes for that C processor. If one is manipulating
the environment with a command line option such as -m32
or -m64, then one likely needs to use the same option
with gcc. Does 'gcc -m32' support "long_long"? If it
doesn't, then you'll need to hack on
gcc/fortran/dump-parse-tree.cc
gcc/fortran/iso-c-binding.def
gcc/fortran/trans-types.cc
