reinstall SIGFPE handler on windows

[quinnj]

While spelunking around Julia this evening, I ran into an interesting bug.

julia> mod(10,0)

Unexpected FPE Error

I'm pretty sure this scares the pants off most people, so I'm wondering if this needs to be caught and return Inf, -Inf, NaN, etc.

Just thought I'd bring it up.

Cheers.

I guess you are using Windows. mod(10,0) also crashed Julia on my Windows Server 2003 and 8.

Yes, newly upgraded Windows 8 here.
