err and warn are BSD format but they are not recommended by library developers. However their consiseness is useful! The solution is to use some macros that create xerr etc which then just map to the error() function. The next problem is error() uses program_invocation_name so we set this to program_invovation_short_name This is a global set but seems to be the convention (or at least errors are on the short name only) used everywhere else.
