Good, I'll amend the script.  Actually, it appears that a lighter weight
libxml can be built with --with-minimum but that option appears to
exclude too much.  So I added --with-output which appears to work.

Thanks,

Yes, that would certainly be the reason.

It's going to be a pain to hide the mingw zlib dll so maybe I'll try to
get the script to use the local zlib.dll.  I used the static lib in the
first place because the dll was causing conflicts with pthread and
caused issues for Qt.  I'll look at this again tomorrow.

Thanks for the feedback.
