did you mean ‘glOrtho’?

I believe this is because sdl12-compat 1.2.70 has an upstream change
that makes it not implicitly include <GL/glu.h>. I've opened
https://github.com/libsdl-org/sdl12-compat/issues/382 to report the
build regression; if it's reverted upstream, I'll cherry-pick that into
Debian, but if upstream decides that they are going to make this change
permanent, I don't intend to make Debian diverge from that.
I think the best solution to this would be: because the affected games
explicitly call functions in the "glu" namespace, they should "#include
<GL/glu.h>" themselves, instead of relying on SDL to do that on their
behalf. (This is an example of the wider meme "include what you use".)
Or, a workaround would be to add -DSDL_INCLUDE_GLU_H to affected games'
CPPFLAGS or CFLAGS, instructing sdl12-compat to continue to be
API-compatible with this particular legacy feature.
