ok, this is done in the attached version of mp_int.m, thank you for the

With the exception of sqrt, I only provided deterministic predicates and
functions, if any error is encountered, the program aborts with error/1.

This version, together with compiling the library with redefined MALLOC
macros seems to work very well. I'll test a bit more an will provide a
PR for "extras" next week.
