Fixed bug #537 Description From esigra 2008-01-07 16:20:21 (-) [reply] I try to get a clean compile for a project using SDL. But I get warnings from SDL headers when I use -Wold-style-cast. This is especially bad because I plan to build the software with -Werror=old-style-cast when we have switched over to GCC 4.2, which has that option. But this problem can be fixed in the SDL headers. I checked out the SVN version and made some patches. See the attached patch.
