- Use up to 256 parameters for programs (as suggested by the parsing while loop), but don't hardcode this values in many other places.
- The passed command line to ntvdm should be as long as MAX_PATH.

Synchronize with trunk again to fix important bugs in the build system.
Implement register control functions which should be exported (Adapted from a patch by Hermes Belusca-Maito).
The actual export is temporarily disabled because a bug in the build system compiles ntvdm as a DLL instead of an EXE.
