It looks like just a > stupid typo to me. 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.
