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.

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.
