This happens with the latest unstable ghc for windows, binary package.
 When I compile a program using at least -O I get a huge list of error
 messages from gcc. The list starts with the following:
 Stg.h: No such file or directory
 HsBase.h: No such file or directory

 Then it goes on complaining about undefined stuff which I assume is a
 consequence of the above errors.
 Stg.h and HsBase.h are located in c:/ghc/ghc-6.5.20060914/lib/i386-
 unknown-mingw32/include/ on my machine. But this path is not passed to gcc
 (obviously). Here's how gcc is invoked:
  c:/ghc/ghc-6.5.20060914/gcc-lib/cc1.exe -quiet -v -I . -I
 c:/ghc/ghc-6.5.20060914\include -I c:/ghc/ghc-6.5.20060914\include\mingw
 -iprefix c:\ghc\ghc-6.5.20060914\../lib/gcc/mingw32/3.4.5/ -isystem
 c:/ghc/ghc-6.5.20060914/gcc-lib/include -DDONT_WANT_WIN32_DLL_SUPPORT
 -DSTOLEN_X86_REGS=4 -D__GLASGOW_HASKELL__=605
 c:\DOCUME~1\JOSEFS~1\LOKALA~1\Temp\ghc2080_0\ghc2080_0.hc -quiet -dumpbase
 ghc2080_0.hc -mno-omit-leaf-frame-pointer -auxbase-strip
 c:\DOCUME~1\JOSEFS~1\LOKALA~1\Temp\ghc2080_0\ghc2080_0.raw_s -O -Wimplicit
 -version -fno-defer-pop -fno-unit-at-a-time -fomit-frame-pointer -fno-
 builtin -ffloat-store -fno-strict-aliasing -o
 c:\DOCUME~1\JOSEFS~1\LOKALA~1\Temp\ghc2080_0\ghc2080_0.raw_s

 I'm running cygwin btw. Let me know if there's anything more you want to
 know.
