When the GCC maintainers include them in the official GCC release.

Get EGCS (I think a DJGPP port will be available soon). It might also be
that your application doesn't actually need PGCC (it typically speeds up
programs by 15%-20%).

It is stable since 2.7.2.1, but there are cases where it slows down your
program. This has nothing to do with stability, it's a consequence of
the small number of registers on the x86 CPUs.
