	I hope that you realize that this may exacerbate problems in the
PowerPC port as well, not just other ports.

	If this patch is widely distributed as an official Linux-PPC RPM
and users rely upon it, it may cause serious problems.  This particular
solution cannot be supported in the general distribution of EGCS.

	I really appreciate the work that you have done in this area and I
fully agree that a real solution is necessary.  I wish that people who
need this support would work to implement one of the better proposals.
