HEAD breakage with mingw-ghc

[Sigbjorn Finne]

Just in case anyone else runs into this situation -- compiling
HEAD with >= ghc-6.0.1 (and perhaps earlier, haven't tried)
produces a wonky ghc/compiler/stage1/ghc.exe. As far as
I'm able to tell, the (mile-long) string literals that Alex outputs
aren't dealt with correctly by one party of the compilation pipeline.
Compiling the various .x files ghc/compiler/ without the -g option
'solves' the problem.
