[XeTeX] Building xetex issues?

[Peter Baker]

Here's another build issue: I've run into the error that was reported 
and discussed here:

http://tug.org/pipermail/tlbuild/2010q2/001372.html

while trying to build on Ubuntu 9.10 (gcc 4.4.1). That is, compile ends 
with this error:

LETypes.h:237: error: ‘UChar’ does not name a type

It doesn't look as if a resolution of the problem was reported in that 
thread; has there been a fix or workaround that anyone knows of?
