--- Comment #1 from Dimitry Andric <dimitry at andric dot com> ---
It appears libgccjit.h and libgccjit++.h are installed into $(includedir), via
gcc/jit/Make-lang.in:

jit.install-headers: installdirs
        $(INSTALL_DATA) $(srcdir)/jit/libgccjit.h \
          $(DESTDIR)$(includedir)/libgccjit.h
        $(INSTALL_DATA) $(srcdir)/jit/libgccjit++.h \
          $(DESTDIR)$(includedir)/libgccjit++.h

This has been the case since David committed r217374. I'm unsure why these
headers seem to be installed only recently?
