Problem starting BC.Exe in DOS 5.02

[mnrvovrfc]

If it is an error with a missing fpu we are going to scrap it.

It's kind of hard without being able to do computations, but it could be kept in situations where "CHAIN" and "COMMON SHARED" could be used, and executable programs are created which require BRUN45.EXE runtime module. Something that people ask from QB64 now and then. It also recalls something else that other people expect from QB64 and other programming systems that recall many decades back: small EXE files which load into memory near-instantaneously. Something else that resembles the situation of the SDL version of QB64: only one runtime module required which is an EXE file, instead of a bunch of 32-bit DLL files.
