Date: Tue, 1 Nov 2005 20:25:10 +0100 From: Dirk Mueller Subject: [PATCH] build SDL with nonexecutable stack libSDL is by default marked with an executable stack, which it doesn't actually need. the reason for this is that there are assembler files in the source tree not properly annotated with the "noexec stack" section. As such the linker does a safe-fallback and marks the whole lib as "requires executable stack". the patch below removes this by adding annotations. As far as I can see it shouldn't break anything.
