Is that the exact commandline? It doesn't work at all here:

$ gcc -E -u -P q.pp
gcc: installation problem, cannot exec 'gpcpp': No such file or directory

-traditional is exactly what makes the difference here:

$ c:/mingw/bin/gcc -E -undef -P -x c q.pp 
 #include "HsVersions.h"
$ c:/mingw/bin/gcc -E -traditional -undef -P -x c q.pp 
#include "HsVersions.h"

I have

$ c:/mingw/bin/gcc --version
gcc.exe (GCC) 3.4.2 (mingw-special)

and get the same behaviour with

$ gcc --version
gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
