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
