Akim Demaille 392f3caef6 examples: beware of the portability of flex --header-file

The option --header was introduced in version 2.5.6.
The option --header-file was introduced in version 2.6.4.
Reported by Bruno Haible.
https://lists.gnu.org/r/bug-bison/2020-05/msg00013.html

So use --header, and do bother with versions that don't support it.

* m4/flex.m4: Check whether flex supports --header.
* configure.ac (FLEX_WORKS, FLEX_CXX_WORKS): Set to false if it doesn't.
* * examples/c/reccalc/local.mk, examples/c/reccalc/Makefile:
Use --header rather than --header-file.

README.md

This directory contains examples of Bison grammar files, sorted per language.

Several of them come from the documentation, which should be installed together with Bison. The URLs are provided for convenience.

These examples come with a README and a Makefile. Not only can they be used to toy with Bison, they can also be starting points for your own grammars.

Please, be sure to read the C examples before looking at the other languages, as these examples are simpler.
