ghc configure

[C.M.Brown]

Hi,

I've noticed that when you run ./configure on a ghc build lot's of
repetition occurs. A lot of the time the same checks are being performed for
each configure file in the ghc hierarchy. Could it be possible if some of
these checks could be done once at a high level and then subsequent
configures could refer to these checks to speed up
configuration time? It's just configuring ghc on a mac G4 is a very time
consuming process in it's own right!

Thanks,
Kind regards,
Chris.
