The builds have been respun with fixes for interrupting Expat properly.

Otherwise, everything from the previous post applies. I’d really appreciate testing. I’ve been advised not to work around the MathML problems, so except for having to figure out how to stop scripts on error, the fix for bug 18333 is now hopefully complete in terms of functionality.

Again, thanks to Mikko Korpela for contributing the Linux i686 build and to Yrjö Kari-Koskinen for letting me use his Linux x86_64 system.
