Ebuild patch from slashem-0.760 to slashem-0.771

This patch doesn't work. It depends on changes proposed in bug 84153 and
doesn't
apply cleanly even after that bug is fixed as proposed.

ebuild patch from 0.0.760 to 0.0.772

The above patch applies cleanly to the current 0.0.760 ebuild in portage. Apart
from this patch, the 'files/0.0.7E6' directory needs to be copied over to
'files/0.0.7E7' and 'va_copy.patch' needs to be removed as it does not apply
cleanly.

The resulting ebuild seems to work fine and I've had a few brief games since
creating the patch.

Also the current 0.0.760 ebuild should be a 0.0.763 ebuild as it does not
install the 0.0.7E6 version of slashem, but rather 0.0.7E6F3

I can't get it to compile with USE="-gnome -sdl" but it works with USE="-gnome
sdl", which leads be to think that something's obviously missing.

This is a dependency problem in the ebuild. Slash'EM uses OpenGL only to
accelerate SDL and that is why compiling with USE="opengl -sdl" leads to error
mentioned above. Ebuild should only consider opengl when sdl is defined too.

OK.

So USE="sdl -opengl" is valid, but USE="opengl -sdl" is not?

That is correct. OpenGL in Slash'EM requires SDL.

Fixes the small problem with USE-flags opengl and sdl

Excellent... added (slightly modified) in portage now...
