problems building GHC from source in Windows

[Andre W B Furtado]

I was trying to build GHC in my Windows XP, using Cygwin, following the
steps in the building guide. I'm stuck in the following error when executing
"make" in fptools:

creating libgmp.la
(cd .libs && rm -f libgmp.la && ln -s ../libgmp.la libgmp.la)
make[6]: Leaving directory `/cygdrive/c/haskell/cvs/fptools/ghc/ghc/rts/gmp'
make[5]: Leaving directory `/cygdrive/c/haskell/cvs/fptools/ghc/ghc/rts/gmp'
../../ghc/compiler/ghc-inplace -H16m -O -O2 -static    -c Apply.hc -o
Apply.o
make[3]: *** [Apply.o] Error 1
make[2]: *** [all] Error 1
make[2]: Leaving directory `/cygdrive/c/haskell/cvs/fptools/ghc/ghc'
make[1]: *** [build] Error 1
make[1]: Leaving directory `/cygdrive/c/haskell/cvs/fptools/ghc'
make: *** [build] Error 1

Any suggestions?
Thanks,
