I'm confused.

The samples you're talking about... use 4.3 compatibility? We already
don't support compatibility profile, so you presumably have to hack
that on.

The ARB_compute_shader extension spec says it requires 4.2, and we
don't expose 4.2 with the compatibility profile. I think you should
have some justification for why it's safe to expose in compatibility
profile, since that's a pretty big change. Or, you don't want to
expose it in compatibility but you need this patch to enable it with
the 4.2-compat hack enabled...?

Strangely, ARB_compute_shader says "GLL, GLC" in extensions_table.h,
but it's only core-enabled on my glxinfo.
