Presently the option guards both direct and accelerated indirect GLX. As<br>
such when one toggles it off they end up without any acceleration.<br>
<br>
Remove the option all together until we have the time to split/rework<br>
things.<br>

Jon, I've not checked the Xwin side of things but considering that the<br>
option is enabled by default and having it for Xwin only will be<br>
confusing I've nuked the guards throughout the tree.<br>

Sorry I didn't get around to testing this before it was committed.<br>
<br>
This breaks my build (See [1]), as the DRI2 loader is now built<br>
unconditionally, which fails without drm.h<br>
<br>
I'm not sure exactly what problem this change is fixing, so I'm not sure how<br>
to address that.<br>
<br>
Is it ok to restore the part which makes building the DRI2 loader<br>
conditional?<br>
<br>

I had a bad feeling about this, fortunately it seems pretty easy to handle.<br>
<br>
>From a quick look nothing in glx/glxdri2.c should require libdrm so we<br>
can nuke the drm.h and xf86drm.h includes, which will get you back up<br>
and going. Alternatively we can add those in a ifdef WITH_LIBDRM/endif<br>
block.<br>

<br>
That's not quite enough, as building glxdri2.c also requires dri2proto headers.<br>
<br>
At the moment, <a href="http://configure.ac" target="_blank">configure.ac</a> only requires dri2proto when --enable-dri2 turns on.<br>
<br>
So either that needs to be made unconditional, or building glxdri2.c made conditional on DRI2 (untested patch attached)<br>
