Gcc flags for compatibility

[Chuck Forsberg WA7KGX N2469R <caf omen com>]

I would like to support development of my programs on my x86_64
Fedora 7 server.  I need to cross compile for other Linux distros
running on 386.  I tried ading   "-m32 -march=pentium " and -m32
to the linker command but the resulting files bomb out with an
immediate floating point exception on other systems including
Backtrack 2.0 and Ubuntu 5.10.  The same source  files compiled
on Ubuntu run fine on Fedora.

Is there a magic "just make it work already" compatibilty flag to use?
