1. wxBitmap - Linux vs Windows, part 2

This is the 2nd minimal program to illustrate the problem.
This time I succeeded in getting it to behave the same way as the original
program (ie, to not work on Windows).

The 1st minimal program works on Windows, this one does not. There doesn't seem
to be any difference between them that would make a difference, but obviously
there is.

-- splash_sample2.exw

-- Replace "bigkick.bmp" with something you have.

Thanks.
