Thanks! I'll see if that could be a gap somewhere in the build
process.  The windows release builds seem to have a pretty ugly logo
on the splash.

Here is the list from build-deps-zips.  I'm fairly sure at least
harfbuzz and jansson should be added, but I strongly suspect the list
in the script is a good one (at least, I like the emacs release
packages Phillip has been creating).

mingw-w64-x86_64-giflib
mingw-w64-x86_64-gnutls
mingw-w64-x86_64-harfbuzz
mingw-w64-x86_64-jansson
mingw-w64-x86_64-lcms2
mingw-w64-x86_64-libjpeg-turbo
mingw-w64-x86_64-libpng
mingw-w64-x86_64-librsvg
mingw-w64-x86_64-libtiff
mingw-w64-x86_64-libxml2
mingw-w64-x86_64-xpm-nox

Removing the intersection of these gives me:

mingw-w64-x86_64-harfbuzz
mingw-w64-x86_64-jansson

However, when I look a little further down the script at the DLLs that
we'll bundle, I note that xpm-nox is missing from the latter list, so
that probably confirms the change needed per comments above.

I will test that I confirm back.

Do you want to patch the documentation while I further mangle Phillips scripts?

PS, not intending to side track the "simpler path" conversation you
are having with Eli, here, but I do think we should carry what we
learn back to the scripts that appear to do the job now.   In all
events, I suspect jannsson and harbuzz should be documented in
README.W32 in *some* fashion.
