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.
