Cross-compiling GTK+ on Linux

I've been setting up a cross compiler environment on my Linux box (Slackware 11). I want to compile a GTK+ application on the Linux box with target 'mingw32' so I can run the application on a Windows box.

This tutorial is the one I used to install a cross compiler, I modified some parts of the script to install w32api 3.9 and only languages C, C++ and G77, binutils 2.16.91 and of course the mingw32 runtime 3.12.

Then I followed this tutorial to setup GTK+, it's header files, to configure the pkg-config files and I used the example 'cross.env' to setup a temporary environment for cross-compiling.

I don't know exactly what causes the problem, below are links to some the source files I tried to compile. One is the compilation error log file and one is the source code of a GTK+ example with a very small script that executes the 'source' command and then invokes the compiler.

NOTE: I did successfully compile without using the mingw32 cross-compiler, however cross-compiling is the problem I want to solve.
