Enter the large time allocator

On December 10, 2019 I fully expected to keep working on the project, but…

… A larger series of personal commitments arrived on my door. I am back working on this project for a limited time.

A few months ago …

I was attempting to write a version of this code for SLD2. I had the following problems:

• loading of external .dll from my programs distribution.
• Interfacing new .dll and the ability of grovel routines to find the gcc compiler under mingw64.

I have been tweeking my emacs and slime setup to allow the use of a mingw64 compiled sbcl. This all seems to work so far.

I want to retry this with the-invaders.
