sometimes one misses the obvious ;-) I'll give the Solaris bootstrap a
try with the Solaris handling in add_options_for_c99_runtime removed.
No idea about Darwin/PowerPC though. If pre-10.3 is supposed to be
supported, the -mmacosx-version-min=10.3 probably needs to go into
rs6000/darwin.h first. Iain?
Once this is resolved, all uses of dg-add-options c99_runtime in the
testsuite can go.
