That's because it's difficult and annoying to build boxi on windows, as I 
only have a windows virtual machine that's on my laptop and it's very slow 
and short on disk space, so I very rarely do it. The last time I did it 
successfully was in 2006, as you can see.

I have not yet been able to successfully cross-compile, although this is a 
more promising route as it should be much faster.

I'm not particularly interested in fixing the old versions, but will try 
to fix trunk.

As above, it's very inconvenient and slow for me. If someone could give me 
access to a decent Windows machine for use for working on this then that 
would help.

It's not obvious that this is a Boxi error. Why is OnAssertFailure 
missing? If you add a #error to the relevant part of the wxWidgets 
headers, does it error out to show that OnAssertFailure is actually being

May have been removed in more recent versions of wxWidgets.

The default is 600 and that is precisely the problem. We cannot compile if 
sys/types.h was included while __MSVCRT_VERSION is set to 600. Therefore 
it must be set to 601 or higher before importing sys/types.h, preferably 
by #including Box.h before sys/types.h, exactly as the error message says.

If you check the output of the failed make, you will see in which file 
sys/types.h was included (perhaps indirectly) before Box.h, and you can 
add a #include sys/types.h in there.

Cheers, Chris.
