glibc/include/stdlib.h
Ulrich Drepper de4a40d07f Update.
* sysdeps/generic/setenv.c: Move setenv code in new function
	__add_to_environ.  Add new parameter specifying already
	constructed string for the environment.
	(setenv): Call __add_to_environ with new parameter set to NULL.
	(unsetenv): Really test all elements for duplicated name.  Missed those
	cases where the two are following each other.
	* sysdeps/generic/putenv.c: Use __add_to_environ instead of setenv.
	* include/stdlib.h: Add prototype of __add_to_environ.
	* stdlib/tst-environ.c: New file.
