Only as much as _all_ ports are still being worked on, except
those deprecated and thrown out.  It's called maintenance, but I
see you already plan for it so enough said.  Or do you refer to
something in particular in the CRIS or MMIX ports?  Anyway, I
feel any and all of my conclusions in the "Porting GCC for
Dunces" document should be taken with a truckload of salt.

IIRC Mike Stump once said something like "8 years to learn gcc,
then a few months per port".

PS.  Don't forget to plan for reading the gcc lists too, now
only a week and a half behind...
