newbie: GHC 6.3 build problem

[Alson Kemp]

All,
  Okay, I've done due diligence on this problem and haven't found any solution,
so I figured that I'd spam the list for help.

  System: Gentoo Linux (freshly emerged...)
          Pentium 3
          GCC 3.3.4

  I'm trying to build cvs-HEAD and am having problems.  The build completes just
fine, but the built GHC 6.3 does not include the "-I" include directories
option for GCC.  "ghc -O2 -v program.hs" shows that gcc is called thusly:

gcc -x c /tmp/ghc10338.hc -o /tmp/ghc10338.raw_s -DDONT_WANT_WIN32_DLL_SUPPORT
-fno-defer-pop -fomit-frame-pointer -fno-builtin -DSTOLEN_X86_REGS=4 -v -S
-Wimplicit -O -D__GLASGOW_HASKELL__=603 -ffloat-store -I .

If I use the Gentoo-built 6.2.2, then the call to gcc is:

gcc -x c /tmp/ghc32417.hc -o /tmp/ghc32417.raw_s -DDONT_WANT_WIN32_DLL_SUPPORT
-fno-defer-pop -mno-omit-leaf-frame-pointer -fomit-frame-pointer -fno-builtin
-DSTOLEN_X86_REGS=4 -v -S -Wimplicit -O -D__GLASGOW_HASKELL__=602 -nopie
-fno-stack-protector -fno-stack-protector-all -ffloat-store -I . -I . -I
/usr/lib/ghc-6.2.2/include

  Help!  How do I build GHC to include the proper "-I" flags when calling gcc?
