No one on IRC knows why an unshared glapi is useful.
It looks like this change stops OSMesa from builing on cygwin (See [1])
I think this is because we never tried building it with shared glapi on cygwin
before, and if we had, we would have noticed that libOSMesa is underlinked,
which is not permitted for PE/COFF shared libraries.
Patch attached which fixes this by explicitly linking libOSMesa with the
shared glapi library.

I'd say commit it. We're planning to overhaul the build system, so if
that patch helps now, go for it.
I also wish it to be committed.
Because "disable-shared-glapi" forbids OpenGL ES 2.
In detail: If we disable “shared-glapi”, DRI2 backend failed to be
loaded, then MESA uses GLX backend to provide render surfaces. But GLX
backend do not support EGL_OPENGL_ES2_BIT. Then user cannot use OpenGL
ES 2.
FYI, there are patches on the xserver list to enable support for
GLX_EXT_create_context_es2_profile.
The patch is a good solution. I vote for it.
