I'm afraid, they are caused by some include files Motorola is shipping
in /usr/include for "var/stdarg"s.  Searching gcc's sources for "saveregs2"
doesn't show any obvious locations.  I'd bet, if you would call

  $ find /usr/include -type f -print | xargs grep saveregs2

grep *will* at least list /usr/include/stdarg.h and /usr/include/varargs.h

I'd suggest you'll analyze, how the include files on your particular
system are treated by "fixincludes"; then you can peek at "gcc/fixinc.dgux"
which contains some fixes for similar problems with varargs vs. stdarg vs.
gcc.  Perhaps, this will give you some insight, how to fix your particular
problem.
