[cvs-nhc98] *.hi files

[Sven Panne]

I have trouble understanding the relationship between the .hi file
below nhc98/include/ and the ones of the same name generated during
the build process (below nhc98/src/prelude, IIRC). Could somebody
please enlighten me?

My concrete problem is that I've changed CTypesExtra (types => newtypes
and added quite a few instances), but the changes don't seem to have
any effect for the nhc98 which is being built. :-(

Cheers,
    S.
