Mps: fix w3i3mv "all" build with vc6:

1. amsss.c: initialize ambigRoot (uninitialized warning);
2. commpost.nmk: 
2a. drop long-vanished protcv.exe;
2b. mpmss.exe needs MVFF;
2c. locusss.exe had no build rule;
3. finaltest.c: main does not use argc,v so declare as main(void);
4. lockutw3.c: add parens to avoid operator-precedence warning;
5. protocol.h: s/interface/interfaceIn: suspected compiler bug.
