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=20
with gcc.  Does 'gcc -m32' support "long_long"?  If it
doesn't, then you'll need to hack on=20
