I think that you only need to match the variables used in the
Makefile.  So the above would be correct, and the following two
should just be omitted:

>     WITH_PYMALLOC=1

Don't forget you'll need to set BATCH as well.

Set the exact same variables as the Makefile is testing.

I believe not, as "defined()" only tests if that name is defined,
not what its value is.
