latest beta + MinGW 3.1.0-1 = minor fix needed

It compiles fine in 3.3.1 with change 2).  I'll commit the change.  I
don't have 3.2.3 installed to test there, so could you try a build
soon Simon?

Thank you, Duncan, it compiles fine with MinGW 3.1.0-1 (@Peter: it uses 
[modified] gcc-3.2.3)

BTW: The "improved" sys/types.h is also contained in the 
mingw-runtime-3.1.tar.gz, so presumably you can use it with the gcc 
3.3.1 candidate as well.

Cheers,
Simon
