In a previous email, you listed only the rtems-supplied patch 
gcc-core-4.1.1-rtems4.7-20070102.diff for the gcc source; have you made 
other changes?

As far as I remember, GCC doesn't build the 5307 libraries unless you 
modify some options for your target.  I made the attached patch for 
building our 5307 gcc.  Without it, perhaps you're getting 68020 code, 
despite the lack of errors?
