are issues. This change simply makes qb64.bas send both the stdout and
stderr output to compilelog.txt.

The purpose of moving the EXEs is so that they are not captured in the

These tests check that we can compile programs that use a variety of
different sets of dependencies. Each program will only be compiled with
the set of dependencies it relies on.
