--- Comment #8 from howarth at bromo dot med.uc.edu ---
At r217144 with https://gcc.gnu.org/bugzilla/attachment.cgi?id=33897 to fix
PR63750, gcc trunk now bootstraps up to the "illegal text reloc" error. Is this
problem understood well enough to debug or should I send a standalone test case
to the darwin linker developer for further analysis of the linkage error?
