Subject: Re: [SDL] SVN doesn't compile for wince

the patch applied for Revision 4483 was seemingly not checked for side
effects.
It broke the WinCE build.
The attached patch should fix these problems. I'm not using SDL 1.2 on
CE anymore, and therefore haven't tested the patch... but at least it
compiles ;-)

Regards Stefan
