From http://gcc.gnu.org/ml/gcc/2009-09/msg00501.html:
we looked at the current list of primary and secondary targets and suggested (again) to demote i686-apple-darwin to a secondary platform on the base that it is unmaintained. We recognize that it is used and gets many bugs filed against. It was suggested to drop powerpc-apple-darwin from the list of secondary platforms.
This was done.
It was also suggested to change hppa2.0w-hp-hpux11.11 to ia64-hpux and to change s390-linux-gnu to s390x-linux-gnu in the list of secondary targets.
Shall we proceed? Paolo
