Why? That demand is just making it impossible to make shared
infrastructure, and I don't think DRM should go off and build its own
stuff just for DRM in a way that nobody else can use it.

If you really, really, care then you can have your makefile codegen an
"allheaders.c" that #includes drm/*.h and compile that.
