- * setenv --
- * Set the value of the environmental variable "name" to be
- * "value". If rewrite is set, replace any current value.
-+ * _cthread_init_routine used to be called from crt1.o to initialize threads.
-+ * This is no longer needed, as initialization happens in dylib initializers,
-+ * but is provided to maintain backwards compatibility. Normally, for 10.5
-+ * or greater, _cthread_init_routine does nothing.
-+ *
-+ * Before 10.5, the _start routine in crt1.o clobbers environ with the original
-+ * stack value, which effectively undoes any environment changes made in
-+ * initializers. When LEGACY_CRT1_ENVIRON is defined, we replace the
-+ * do-nothing routine with one that attempts to restore the environ value.
-+ * But this only works if the setenv (and family) routines were used
-+ * exclusively, (no direct manipulation of environ). Note that according to
-+ * SUSv3, direct manipulation of environ may result in undefined behavior in
-+ * setenv and family, so we don't support that (on less than 10.5).
