The problem is that the headers from the jpeg library actually need to
be patched to work on windows because otherwise there is a clash with
the 'boolean' typedef. I didn't want to do this because it causes all
sorts of different problems, so I chose the solution the wxwidget
library uses, by defining the preprocessor variable HAVE_BOOLEAN and
providing a definition for jpeg's boolean type.
I patch the image toolbox source code as follows:
