version 3 of the patch survives a full regression test run
on both FreeBSD 4.8 & 5.1, with USE_RECURSION_LIMIT reverted
to 10000.

Thanks for testing it!

Here is another implementation (version 4), using a
different approach. Unlike the other implementations, this
one doesn't recurse at all, and introduce no new opcodes in
the engine.

Version 5 fixes a minor bug due to a variable being used
inside a macro and a submacro. Now submacro allocates it
internally to avoid further problems.

I assume this patch can be closed as outdated?
