The build was done using ghc-0.29 (which I compiled from .hc files some
time ago) and slightly modified gcc-2.7.2.1 for the following
fptools/mk/build.mk configuration:

  ProjectsToBuild=glafp-utils literate ghc hslibs
  GhcWithNativeCodeGen=NO
  MKDEPENDHS_1_2=mkdependHS-0.29
  GhcCompilerWays=p
  GhcHcOpts=-O
  HsLibsWithReadline=YES
  ReadlineIncludePath=/usr/contrib/include

Profiling seems to work, though I didn't test it too extensively.

The following patch shows most of the changes I had to introduce to make
the compilation work.  I also needed to modify paths at the top of the
fptools/literate/mkdependlit Perl script and increase the heap size to
compile several files.

There is some goofy code (function *definition*) in one of IRIX C
headers that deadly confuses GNU 'as'.  If you run into problems you may
wish to have a look at my gcc-2.7.2.1 binary kit which has some headers
fixed.
