Bison requires GNU m4 1.4.6 or later. See
https://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz.
## Running a non installed bison
Once you ran `make`, you might want to toy with this fresh bison before
installing it. In that case, do not use `src/bison`: it would use the
*installed* files (skeletons, etc.), not the local ones. Use `tests/bison`.
## Colored diagnostics
As an experimental feature, diagnostics are now colored, controlled by the
`--color` and `--style` options.
