/* __USE_POSIX, __USE_BSD, and __USE_BSD_SIGNAL used to be defined either
   here or with -D compile options, but __ macros should be set and used by C
   library macros, not Postgres code.  __USE_POSIX is set by features.h,
   __USE_BSD is set by bsd/signal.h, and __USE_BSD_SIGNAL appears not to
   be used.
