Could someone commit the patch in comment #7. It cannot make the matter worse
than it is without it.
TIA

The size of the pointer (which can be useful sometimes but not in this case).

Currently at stage 2 for revision 164490 on powerpc-apple-darwin9 with the
patch in comment #5. Thanks.

Side question: what could be the meaning of "sizeof (struct cl_decoded_option
*)"?

------- Comment #4 from iains at gcc dot gnu dot org  2010-09-23 09:34 -------
this appears to be to do with the driver construction of a default
macosx-version-min.

./gcc/xgcc -Bgcc -dumpspecs => bus error

./gcc/xgcc -Bgcc -dumpspecs -mmacosx-version-min=10.5 => completes normally.

Initial debugging suggests that the constructed option is being flagged as
error=4 (wrong language)
