Hi, Ralf

on my yeeloong laptop, with dash(0.5.5.1-3) in o32 ABI, it also can only
execute 32-bit numbers, but on my thinkpad SL400(i686, dash version is
0.5.5.1-2), it works well with 64-bit arithmetic.

So, it means dash not always works normally, perhaps there is a bug
there, or the bug only exists on MIPS machines?
