Changing the condition is one option. I was actually going to suggest
updating to a more recent copy of gmp which replaces this with a build
time check that's run from the configure script. I don't know whether
an update is actually feasible though.

I'm going to report any issues I find to the GHC folks, yes.

OK, thanks for confirming.

Is that ghc itself? I ask because I've seen both haddock and ld run amok
when building Haskell apps before.

The machine the build is running on is PXA 270 based and has 256MB of
RAM and no swap. Also, the box appears to be running out of disk
space...
That said, I wonder whether the current duplication of efforts is any
good. I'm probably going to leave the current build running (unless the
machine is needed for something else) because I want to know whether
what I've done leads to a working compiler but do you think there's any
point in me continuing beyond that point? AIUI, you've got a second
stage compiler built already?

Makes sense.
