First, a nit:  the renamed environ is a structure field, not a 
variable.  (I would have used "env" instead of "environ_p" but that is 
just bikeshedding.)

Second, you are still adding $(LIBS) to the build rule for mkheader and 
you should mention that as you previously did.

Lastly, I am probably more impressed than I should be that this is all 
you actually need for a z/OS port.  (The other system that I know of 
where "environ" is a macro is not a POSIX system.)
