Fixed bug #157 [patch tweaked to handle older nasm, which doesn't support :function syntax] ------- Comment #5 From Mike Frysinger 2006-05-22 01:24 [reply] ------- Created an attachment (id=132) [edit] libsdl-hidden-nasm.patch here's the patch i posted here: http://www.libsdl.org/pipermail/sdl/2006-March/073618.html this will hide the symbols dynamically if the build nasm/yasm supports the hidden stuff ... in other words, this patch should be safe with both older and new versions of nasm/yasm
