Sorry for the delay in response - your message got caught in the

Thanks for suggesting "^[0-9]+" as an alternative.  We have gone through
several different regular expressions since the 2.04 release in an
attempt to exclude strange newlines and pre-processor directives.  Your
solution might be the cleanest.

There is definitely something odd happening here.  The version in
    Hat/Foreign/ForeignPtr.hs
has already been transformed by hat-trans from
    Foreign/ForeignPtr.hs
When you copied it back to that location, the Makefile then tried to
transform it a second time, which is the reason for the subsequent
error:

> hat-trans: ./Hat/Hack.hx: openFile: does not exist

But I am not sure why the original file
    Foreign/ForeignPtr.hs
was no longer in its original location.  It is certainly included in the
tarfile, and 'make clean' should not remove it.  Perhaps you just need
to start again with a freshly unpacked archive and the
'script/confhc-hat' fix?
