Filing bug on this warning:
> layout/mathml/nsMathMLmunderFrame.cpp:285:11: warning: unused variable 'xHeight

Looks like this variable has actually been unused since it was first added, back in the year 2000:

GCC only recently started warning us about this, though, because this variable had been set by passing it as an outparam -- which looked like we were 'using' it -- up until zwol tweaked it to set it directly, in Bug 174055 part 6.

Attached patch kills the variable.
