yes -- the "--enable-reeentrant" option wraps the global variables as
functions to keep them from being modified except via a function (which
lets one add a mutex or whatever).

ABI 6 doesn't have to use that option, but the reentrant feature relies
on ABI 6.  Normally the libraries are named differently (with a "t" on
the end).  Naming them the same - that is a problem for this case.
