That's really weird.  I'd rather not do that if it can be avoided.

Surely they can't expect every library that accesses environ to get a
system-specific change?

Does it work to take the declaration of environ from <stdlib.h>
instead of giving an explicit "extern"?  The autoconf way is normally
to let the headers do the job where possible.
