	Clearly lots of people appreciate the zenity build-progress thing, and
those that don't like it already turn it off, so it'd be fine to improve
it in :-)

	Well - the problem with this is that (by design) tail_build is a single
make instance that compiles ~all of LibreOffice :-) As you say, that
does break the usefulness of the zenity output - but it also makes it
really rather hard to extract the progress information I'm afraid.

	Of course; the question really is how best to do that. There is a
fairly firm consensus against building our own gnumake, so - I wonder
what ways we could use to extract the information. Clearly having
build.pl parse and interpret the compile output might be one approach,
but it's unclear from a tail_build 'make' how many files will require
re-compilation (though make knows that after it has done it's big
dependency thrash at the beginning).

	So - it prolly requires quite some thought :-)
