  Hi Carlo.

  Sscanf _does_ follow locales. I had that very nasty experience myself
not so long ago! I opted to make a small routine that scans the input
string, and replaces any ',' to a '.' or vice versa.

  This is very disturbing, as many programs generate numbers with '.' as
decimal separator, and the data cannot be imported into comma-oriented
country.

  Changing the locale solves that, but introduces _many_ other problems.
You can change the LC_NUMERIC part of the locale only, which is the best
solution if you don't want my solution (the routine above).
