Yay, I broke things ;-)

There's a couple of routes we can take:
 - Bring back the EGL/GLX includes - I would strongly advice against that.
 - guard the typedefs with ifdef macros - fragile, we'll also need to ensure that the header is included after the EGL/GLX ones.
 - opencode/replaces the existing typedefs with the respective original types - a tad nasty, yet it seems like the better option.
 - other ?

Vinson, let me know which one you'd prefer and I'll whip a patch... Unless you beat me to it.

Emil, I don't have a preference but I tested that undoing the changes in 8472045b16b3e4621553fe451a20a9ba9f0d44b6 fixes the build.

Sigh I'm starting to loose my cool :-\

Vinson why did you opt for the option I _explicitly_ mentioned is a _bad_ idea ?

Yes, this particular workload broken, yet reverting the commit (as you can see in git history) will break a lot more workflows.

Guess I should stop being nice and call people(?)/their work names. Yet I seriously want to avoid that where possible.

/me tests some 2wo local patch

Hi,

I need to report that Android build has been broken by Vinson's commit mentioned at Comment #3.
