Subject: Re:  [4.0 Regression] Ada Bootstrap failures on powerpc-darwin with undefined symbol (__Unwind_fallback_frame_state_for)

As a workaround, I've changed all instances of -lgcc -lgcc_eh in the specs
file to -lgcc_eh -lgcc -lgcc_eh.  With this change, the bootstrap got
further along:

The file compiles without problems at -O0.  Is this a known bug, too?

Created an attachment (id=7569)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=7569&action=view)
patch which moves darwin-fallback.o to the correct static library

Using your hint for -lgcc -lgcc_eh -lgcc, well the patch which would do that
not be the correct fix but I figured out what was going on.

Oh, by the way the ICE you got is not known yet, please file it seperately.

Fine.  I said the change above was a hack, and I wasn't sure whether it is
the correct solution.

> Oh, by the way the ICE you got is not known yet, please file it seperately.

Ok, will do.
