GCC should have some analog to libclang:
i.e. a somewhat stable API that makes the AST available without exposing
too many internal details.

Maybe that is possible with a GCC plugin, but since GCC could have
offered such functionality since decades, it's likely that it was
prevented for some political reason (like "you could then use GCC's
front-end for a proprietary IDE").

Maybe nobody bothers because using clang is easier than to fight with
FSF policies.
