The exports definition file for gcc29160.def is automatically generated
during each libgcc build. Theoretically it should remain the same in
future versions of egcs, until the version counter will change,
however, and for future reference, I've included it here.

Also here is included a batch file called make_gpp.cmd which will postprocess
libgcc and create separate versions of libgcc for C and C++ programs (with
and without exception handling). See the comment at the start of batch file.
