Peter opens a can of worms

Peter E writes (in elog.h):

+ #ifndef __GNUC__ extern void elog(int lev, const char *fmt, ...);
+ #else
+ /* This extension allows gcc to check the format string for consistency with

+ extern void elog(int lev, const char *fmt, ...) __attribute__ ((format (printf

+ #endif

Cool.  Now who's going to fix the cartload of warnings this has
produced?  I'm counting about 125 of them.  They should be fixed,
on grounds of portability, but the main problem right now is that
it's difficult to see the *real* warnings because of all these
guys...
