Update.
* conform/data/stdlib.h-data: Account for XPG6 changes. * stdlib/stdlib.h (__random): Change return value type to long. (posix_memalign): Cleanup parameter names. (setenv, unsetenv): Make available for __USE_XOPEN2K. Change return type of unsetenv to int. (qecvt, qgcvt, qfcvt): Declare only if __USE_MISC. * sysdeps/generic/setenv.c (unsetenv): Change return type to int. Return -1 and set errno if parameter is invalid. * stdlib/random.c (__random): Change return value type to long.
