Oh, I see!  The build includes both 64-bit and 32-bit modes (so that
the -m32 option will work), so I get the error when the build
process gets to that point.  What preprocessor symbol can I use in
my code to identify 64 versus 32 bit modes for conditional
compilation?  Do GCC's Makefiles set __x86_64__ and __i386__?

Have a look:

gcc hello.c -E -Wp,-dD

will show you everything that's defined.

Andrew.
