I have to admit I haven't been following the development of Cabal
too closely.  I am still using my own Makefiles to build HaXml, and
these tweaks only affect that process.

My (possibly erroneous) impression is that the .cabal file is
essentially what I need to supply as the input to 'ghc-pkg register',
with the caveat that it needs a few extra fields to locate the
interface files, library archive, and so on.

What the recent commit does is to add exactly those fields (to
a copy of the .cabal file) just before registering the package.
The top-level .cabal file remains unchanged, so if anyone is using
Cabal as their build system instead of the supplied Makefiles, things
should continue as normal for them?
