OOOh that explains a lot! ;)
Thank you guys very much!!!
I should say that the confusion comes from math (as in math 5.4 *is* greater 
than 5.31). So it is a little deceiving...

Another source of confusion is that in the supposedly official website for the 
Flex project (http://www.gnu.org/software/flex/), latest version available on 
mirrors is 2.5.4.

And the Flex for Windows project 
(http://gnuwin32.sourceforge.net/packages/flex.htm) also has 2.5.4a as its 
latest version.

So I should like to ask here why there seems to be two different releases of 
the Flex project.

Thanks a million,
