because jasper@ wants the cpphs library.
Put the library into a separate subpackage (hs-cpphs).
Shorten DESCR-main (formerly DESCR).
Tested with both ghc and nhc98 (the latter on armish).
Tweak WANTLIB (gmp only required when built with ghc).
Take maintainership.
Not that some regression tests fail. This will be fixed in the next
release.
