	13	* wield the One, and you know that well, so do not trouble to say we!"

	15	* This file contains a collection of automatically created wrappers
	16	* (created by running reentr.pl) for reentrant (thread-safe) versions of
	17	* various library calls, such as getpwent_r. The wrapping is done so
	18	* that other files like pp_sys.c calling those library functions need not
	19	* care about the differences between various platforms' idiosyncrasies
	20	* regarding these reentrant interfaces.
