This problem is caused by this pseudo having a preferred class of
INDEX_REGS and an alternate of GENERAL_REGS, even though it *can't* use
GENERAL_REGS.
Is this a bug, or am i just supposed to have a one-line hack for this that
doesn't let it use the alternate class if the preferred class is
INDEX_REGS.

Hmmmm. Interesting.
Turn debug_new_regalloc to 2, and send me the stuff sent to stderr.
I'll do that as soon as I"ve rebuilt GNAT, as I was testing the
regular C in the mean time and had to reconfigure for that.
Anyway I got the regular C bootstrap to go a bit further by
killing a hanging conftest on the second configure, and it showed
an error that's probably easier to tackle:
