Error building GHC 6.8.3 with MinGW 4.2.1-2 dw2

I try to build a lite version (e.g. no extra libs) of GHC 6.8.3, I'm using
MinGW GCC 4.2.1-2 with dwarf-2 exception and pre-compiled GHC 6.8.3. Here's
my configure:
sh configure --prefix=/c/ghc-new CFLAGS='-s -O2' LDFLAGS='-s -O2'
--with-gmp-includes=/usr/local/gmp/include
--with-gmp-libraries=/usr/local/gmp/lib
And my make:
make bootstrap3

But in the middle, I got this:
Preprocessing library hpc-0.5.0.1...
