Yes, it is definitely a stupid typo, and I don't think this alone fixes
anything significant, but there appears to be another bug underneath.
Without -DUM_FASTCALL, I've been seeing the kernel panics we previously
discussed. There appears to be some other bug that exists at least as
early as 2.4.24-1um, triggered when UM_FASTCALL is not defined. I've
verified that this is the case with the following versions:
2.4.24-1um
2.4.24-2um
2.4.24-3um
2.4.25-1um
2.4.26-1um
The panic I'm getting is very repeatable--every time I run the j2eesdk
installer, it'll panic, but if UM_FASTCALL is defined, it runs just fine.
