Any code so protected that isn't included as part of (one of)
lib{dri,drm,glx,GLcore}.a in the X server, is dead code. Which explains why
linux-dri doesn't use that code, since linux-dri doesn't build the
server-side modules.
GLcore is the tricky part, since that's the indirect renderer. The rest of
the modules probably don't overlap with the solo code at all.
In other words, those defines don't affect sharing *_dri.so between X and solo
because those modules are never loaded by the X server. Any code that's
going to end up in the X server will be in the core or the software
rasterizer as part of libGLcore, which I will eventually do away with. In
the meantime, if you're adding code that will make it into GLcore, wrap it
with the X ifdefs for now; but this shouldn't affect the DRI drivers at all.
