XSB Src (SVN)-old

airplane hacking. adjusted error handling so that, among other
things, the compiler doesn't go into an infinite loop when you type

table p/1 as X.

Airplane work... Documented table preds as options.

Adding these (note done before).

Adding this for constraint_tests.

... and another one ...

Forgot to commit the extern statements for Varenumerator_trail_top.

Initializing VarEnumerator in subsumptive answer search. This is
used to copy in conditional answer information, and will hopefully fix an initialization error detected by valgrind.

Changes to fix a bug in find_components, which is still under development.

Defining use_module/2 in terms of import/2. This makes XSB a bit more
compatable from the command line (compiled code is already handled).

Trying again...
