+ * 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.
+
* sysdeps/i386/bits/string.h (__memset_cc): Fix typo in last patch.
* nis/nss_nis/nis-initgroups.c (_nss_nis_initgroups): Correct size
