>Description:
The C testsuite has excess errors running with -march=1.0,
caused by Internal Compiler Errors.
It is unlikely that there are hppa1.0 boxes running HP-UX
or MPE/iX that need to run gcc, so the mpeix default
could be moved to hppa1.1 and this be prioritorized based
on any embedded hppa1.0 clients.
