Right? Yeah, remember I when I had first started building those
weekly binaries, someone noticed that they were considerably
bigger compressed files ... or some such. Anyway, I had built
all of the new image dll's and built the weekly Emacs and I
think, a pretest or a release ... probably release, right? And it
didn't go over well because of licensing. I took 'em all out and
used only the freshest headers. That's when that started ...
with making the new libxpm and so on. Sorry for making the
buuug.
