That would not work with (see my 1st email):

$ bison --version
bison (GNU Bison) 1.35
$ flex --version
flex version 2.5.4

Great fun, if everyone would think they've grown so big and important,
it would warrant a diversion from a resonable standardised version
string.

Currently, we just use $NF, which has worked for all tools up till now,
but I can imagine inserting something like:

    | sed 's/[^0-9]*$//'

However, with the current:

   gcc (GCC) 3.1.1 20020606 (Debian prerelease)

this would yield '20020606'.  I don't like the idea having to go the
way of

   expr "$ver" : '.*[^-.0-9]\([0-9][0-9]*\.[^ ]*\)'
