Akim,
The Ox attribute grammar evaluator generator compiles, links, and passes its
regression tests under macOS Big Sur (v11.5.2) using this version of Bison with
the following C++ compilers:
- Xcode (12.5.1): g++ reports its version as ‘Apple clang version 12.0.5
(clang-1205.0.22.11)
- GNU (Homebrew): g++ reports its version as ‘Homebrew GCC 11.2.0) 11.1.0’
- LLVM (Homebrew): clang++ reports it version as ‘Homebrew clang version 12.0.1'

I don’t currently have the time to run the regression test suite over the full
set of portability configurations. I hope to get to that later this coming week.
Thanks!
Tom
