Date: Fri, 24 Apr 2009 17:47:07 +0200 From: Stefan Klug 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
