On of the points of getopt is that -fFLAGS and -f FLAGS both work  
without any extra code.  Standard getopt doesn't do optional arguments  
at all; GNU getopt handles -vn, -v n, and -v -- or -v -x (for random  
options -v, -x, the former taking an optional argument; the latter two  
cases are recognized as argument omitted).

(That compilers behave differently is not, IMO, a good thing --- but - 
l is problematic at best.)
