I ... think so ... Nope, I take it back. Yacc is found regardless.
The problem is that changing jamgram.yy causes yyacc to run but
doesn't cause yacc to run again.

...found 44 targets...
...updating 6 targets...
.cc bin.ntx86\yyacc.exe
yyacc.c
.yyacc jamgram.y jamgramtab.h
.cc bin.ntx86\mkjambase.exe
mkjambase.c
.cc bin.ntx86\jam.exe
