--- Comment #11 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-05-29 15:12:50 UTC --- It is strange that regress is still able to bootstrap powerpc-apple-darwin9 with r174286 present. The powerpc-apple-darwin9 target also has... auto-host.h:/* #undef HAVE_GAS_WEAKREF */ but it doesn't seem to trigger the same bootstrap issues as on intel darwin.
