Microsoft C/C++ 7.0 and 7.01

Most of YAMP now compiles under Microsoft C/C++ 7.0. Minor modifications were made throughout the code for this compatability. The graphics module still requires Borland graphics routines. I might add a presentation grahics module using the MSC functions later. It should be pretty easy since I don't have to write the scaling and axis functions again.

There is one minor difference between the Borland and MSC v7.0 in-ram versions. The virtual vector, mm, is a huge pointer in MSC and it is a far pointer in Borland C++. I had trouble getting the MSC version to release all of mm if it was a far pointer. However, under full optimization for speed, the MSC code is much faster in the in-ram version. Performance is identical in the virtual memory model.

A patch to MSC v7.0 has been released which fixed the problem above. The value of HUGE_POINTER is set to __far for the patched version of v7.0. The new version is 7.01. If you have not applied the patches you must change __far to __huge to avoid the memory leak.

I have only tested the MSC version in the large memory model. It does not compile in the small memory model.
