RMS does not want additional baggage accompanying the +@code{error} module, so an LGPL user must provide their own +replacement @code{program_name}, and a GPL user should manually +specify using the @code{progname} module. + +Additionally, using the @code{progname} module is not something that +can be done implicitly. It requires that every @code{main} function +be modified to set @code{program_name} as one of its first actions. |
