Thanks, though it occurs to me that neither the old or the modified version
cover the case of the OpenBSD flex port which has a binary called
'gflex' as there is a different version of flex in the base system.

So perhaps a simpler test still is in order?

The base version seems to include the full path as well.

$ flex --version
flex version 2.5.4
$ gflex --version
gflex 2.5.35

$ /usr/bin/flex --version                                                      
/usr/bin/flex version 2.5.4
$ /usr/local/bin/gflex --version                                               
gflex 2.5.35
