Until we have a decent reimplementation of glr.cc, we have to use tricks to shoehorn C++ symbols to the C engine of glr.c. Some of them are done via #define. Unfortunately in Bison 3.6 some of these we done in the header file, which broke valid user code. Reported by Egor Pugin. https://lists.gnu.org/r/bug-bison/2020-06/msg00003.html * data/skeletons/glr.cc: Stop playing tricks with b4_pre_epilogue. (b4_glr_cc_setup, b4_glr_cc_cleanup): New. Much cleaner way to instal glr.cc's scaffolding around glr.c. * data/skeletons/glr.c: Adjust to use them.
