Of course... as stated in environ(7):
"Shared libraries and bundles don't have direct access to environ, which
is only available to the loader ld(1) when a complete program is being
linked. The environment routines can still be used, but if direct access
to environ is needed, the _NSGetEnviron() routine, defined in
<crt_externs.h>, can be used to retrieve the address of environ at run-
time."
It has always been this way on OS X, so Keyan's patch is correct.
