Small test of strtoul showing bad behaviour with 64bit wine

Howdy ho, I and Lee were messing around with some 64bit applications built via
mingw, and much to our chagrin, something was reading the numbers incorrectly.

We got the expected results on native Linux, native Windows (both mingw and
msvc bins tested), but not on 64bit wine IF we built with mingw.

Investigating, we tracked it down to wine's implementation of strtoul.

I've written up a small test case showing our use of strtoul. It should also
reliably reproduce the errors provided it is...

1. built as a 64bit Windows application;
2. strtoul is not inlined;
3. It's executed in wine
