I think the same thing happens with x font-backend when
iso10646-1 font is requested. But, it doesn't cause a
problem on GNU/Linux.
I managed to install mingw and msys, and built Emacs with
them. Then, I started Emacs, set the defualt font to "Arial
Unicode MS", and insert many #x2203 characters. But, I
can't reproduce the problem.
By the way, I also installed gdb-6.8-mingw-3.tar.bz2. But,
with "M-x gdb", pp and pr commands doesn't work. They print
nothing. They do work when gdb is invoked from command
line. Do you know what is wrong?
