[Box Backup] Cross-compilation with i586-mingw32msvc under Ubuntu Hard

[Achim]

Hello Chris:

This time I got a lot further, but there are still some issues. Now the 
linker is complaining about undefined references to `_regfree' et al.

I have used PCRE 6.3 for this compilation, I will try the newer versions 
once we get the original configuration runnning.

Details are included below.

Cheers, Achim
