Explicit specification of .h files on the command line is mainly
supported for backward compatibility with old versions of c2hs.  The
suggested way of handling this with the current c2hs is to have a
"#include" in the .chs file.  (This does *not* require to run cpp over
the .chs file.  c2hs understands and interprets cpp directives
directly.)

It would be nice if future versions of Cabal could directly support c2hs
instead of requiring explicit setting of "hookedPreProcessors".  If I
can help with this, let me know.  In the long run, I want to change
c2hs' build system over to Cabal, too.
