Looks like Symbian doesn't comply to the ARM exception handling ABI
and/or the toolchain is not set up for that. Anyway, I've disabled
this now for Symbian. Please git pull and try again.

Yes, and Symbian doesn't have log2/exp2/trunc :( I have to add a math-fixed.h in lj_ir.c, lj_opt_fold.c and lib_math.c

the Symbian port is compile ok, but I like to test in my PC Box before install it on my e72i, and I find a strange place:

I build lua51.lib using msvcbuild.bat, and it works good (I notice a great performance improve on Windows), but, when I buildvm for five .h file and lj_vm.obj, and put all source into my project, the program hit a user break point (int3) in lj_BC_JFUNCV, I noticed that is not Implement, but the question is, Why the same lua sources, the same other sources and lua51.lib don't hit this breakpoint but in my own project it touched?

but after all, thank you very much for such a great miracle:)

I notice that new HEAD in git repo add exp2/log2 support for symbian :)

this patch add missing stdint.h for lj_def.h:
