Great, thanks for your help Ian.  Building GHC with
"INTEGER_LIBRARY=integer-simple" is exactly what I was looking for.
So naturally though, I'd like to avoid maintaining an internal branch
of GHC.  Are there any plans to make integer-simple the default
integer library?

I was able to build GHC on Linux with no trouble. But on Windows, I go
down because (I think) the preprocessor is choking on ^M characters.

I get errors like this:
libraries\haskeline\.\System\Console\Haskeline\Backend\Win32.hsc:153:
error: syntax error before ')' token
libraries\haskeline\.\System\Console\Haskeline\Backend\Win32.hsc: In
function `main':
libraries\haskeline\.\System\Console\Haskeline\Backend\Win32.hsc:155:
error: syntax error before ';' token
compiling libraries/haskeline/dist-install/build/System/Console/Haskeline/Backend/Win32_hsc_make.c


After removing those ^M's from Win32.hsc and Win32_hsc_make.c, things
are moving along, slowly but surely.  The build is using the "inplace"
gcc so I assume the problem is not gcc, but whatever generates those
files.  Any idea how the extra line feeds slip in?

Thanks,
Greg
