I don't know if this helps, but I've noticed a lot of instability with the more recent SVN versions myself lately, you're not alone.
If you're looking for a beta that is more advanced than the stable release (and with fewer instabilities than the SVN), I'd recommend grabbing the latest pre-compiled one from the beta site that Mattn occasionally places there. The SVN version is almost always under constant development, and depending on when you grab it, it may or may not work.
Also, the pre-packaged codeblocks and MinGW package is out-of-date. Codeblocks recently released a new version that I've found works fine to compile the game, along with the latest compiler from sourceforge.
Not being a C coder I don't know what your error messages mean, however.
EDIT: What I did to make the game compile properly (and I admit this probably isn't the best method) was I first set up the old prepackaged codeblocks with the extra libraries included, then installed the up-to-date codeblocks program (from the codeblocks site, they just released a new binary) and the latest compiler on top of that (MinGW from sourceforge), so the updated compiler program would have access to the extra libraries (after linking everything in the codeblocks option menus).
This resulted in my case in getting the SVN versions to compile free of errors or warnings. BTW, looking at your hardware specs, you have a setup much like my own desktop, which also runs Windows MCE on one of its partitions (and therefore I doubt the issue is with your hardware).
