The "patches" turned out to be smaller than I had imagined. The relevant
portion was only two lines in configure.in (attached). Cygwin places the
*.dll files in /usr/bin and the *.dll.a files in /usr/lib. I think gcc
can use .dll directly, but the search path usually does not contain
/usr/bin.

Arial is supposed to be identical to Helvetica, that's why I thought the
substitution was fine.
However, I had misdiagnosed the problem. I have Helvetica on my Windows
PC from some Adobe software. But cygwin fontconfig doesn't find it. For
some reason, fontconfig picked up the bitmap version of Helvetica in my
previous trials. Now it picks up "Bitstream Vera Sans", which is a very
different font. I still need to get to the bottom of this.

It's not too hard to specify the library path using --with-tcllibs and
--with-tklibs, so no need to rush here.
Thanks,
