*Broken* on many platforms? It is not broken. It is not enabled
on most because most have not had their scheduling information
un-lobotomized to *utilize* the Haifa scheduler. The i386 port of
GCC/EGCS does not have any scheduling information and the Haifa scheduler
does not provide any benefit and may actually be a slight loss.
The Haifa scheduler only is enabled by default on the HP and Alpha
ports in egcs-1.0.x.
I am not sure how NetBSD is integrating EGCS, but EGCS is *meant*
to be built using "make bootstrap" not simply "make".
