simonmar-win32-head, build 113, Failure

[Edward Z. Yang]

Manually hacking around this results in another Windows build error:

'ghc-stage2.exe:
C:\cygwin\home\ezyang\ghc\libraries\integer-gmp\dist-install\build\HSinteger-gmp-0.2.0.0.o:
unknown symbol `___chkstk''

I can't tell if this is because my horrible hack is wrong or that
more things are broken. >:-(

Cheers,
Edward
