while looking in the graphite backend code I stepped over a commit

Would your implementation also handle two locations for tokens that
come from macro expansion?
macro expansion are tricky to handle as far as I could see, so currently
this is not handled. It's tricky because some locations are real in
the source, and some are virtual from the macro.

On Linux/ia32, revision 139326 gives

FAIL: Divide_1 -O3 -findirect-dispatch compilation from source
revision 139311 is OK. The possible causes are revision 139325

This test also fails recently for avr-unknown-elf.
Also fails: weak-2.c, weak-3.c, weak-4.c, weak-5.c, weak-12.c.
May be related: also fails on gcc.dg/attr-weakref-1.c.
These tests are known fail revision

I've added a check to Classpath CVS for 0.7.9 and this should make GCJ 4.4.
Do we need this backporting to anywhere else or is this sufficient to close
this bug?
