No, please don't pass hsc2hs/Main.hs through cpp :-)
It corrupts __GLASGOW_HASKELL__ in strings (because of string gaps).

I moved the system-dependent thing to KludgedSystem (it should be
named better as it no longer contains only the system function)
so it does not require cpp.

(I keep it in sync with QForeign, which is easier if the same source
can work in both places.)
