My compile flags are -Wall -Wextra -fno-common -fexceptions
These are not enough to trigger the warnings, the gcc 4.6.3 I use
needs at least one of
-Wall -Wformat -Wno-format-extra-args -Wformat-security
-Wformat-nonliteral -Wformat=2

With regard to r.lake, the warnings seem to be bogus because the
contents of the message strings are out of user control.

If these warnings should be fixed, I guess the right place is either
fixing the _ macro or G_message(), G_warning(), G_fatal_error(). Any
user input always goes first through the parser, thus the parser could
be modified and afterwards the extra format-related -W flags are no
longer needed.

In any case it seems to me that fixing that for every instance of
G_message(), G_warning(), G_fatal_error() and any print functions is
not really feasible.
