doesn't let it use the alternate class if the preferred class is

  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

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:
