[GRASS5] flex/lex, compatibility

[Andreas Lange]

Hi Michel,

the change will be implemented with the configure system.
But now the problem is that one module uses an option only recognized by
flex. On Linux this causes no problems as flex is always installed (and
called either as flex or with a shell wrapper that calls flex -l). But
the old lex implementations choke on this option.   
As David pointed out there may be other incompatibilities, which can be
avoided by making flex a prerequisite.
On systems without flex only some modules compile and i can see no sense
in "downgrading" the other modules to be compatible with lex. 

cu,

Andreas
