Looks good to me (for the trunk), Zack.   I'm travelling and can't
test it but if you've verified that we don't have things including
the files you're vaporizing, I'm cool with it.

I'll try to answer for the IA32 targets.

ISC was bought by Sun in the early part of the decade and ceased
to produce a product under that badge.  Other than a token Y2K fix
a few years ago, this has been dead for a long time.   It was officially
EOL'ed recently.  I can't recall seeing a success or failure report or
a question about it during my stint with GCC.  When I was at an IHV that
was heavily involved in the PC UNIX market, I think we dropped ISC support
in the mid 90's and nobody noticed.

Without knowing what exactly the "sysv*" stuff is trying to match, I'm
guessing that a catch-all for the esoteric Unixen like Dell, UHC, Esix, 
Consensys and such.   I think those are even less likely to be in active
use than ISC.     If, OTOH, it matches something else, then it might be
less dead than I'm suggesting.

AIX for the PS/2.   Eeeeek!   Bad memories.   I'll let Dave have the 
final vote, but I'm pretty sure this one is quite dead, too.

The MIPS Magnum before MIPS was bought by SGI. More bad memories.   I 
still have the processor out of mine mounted on the wall - I delighted 
in ripping the chips out of that piece of junk. :-)
