Actually the cp -f command in common.mak does cp -f
$(SLIBNAME_WITH_MAJOR) $(SLIBNAME). To keep make happy we let a bad
SLIBNAME_WITH_MAJOR get built then replace it with the good DLL that
dllar.cmd delivers. It is somewhat redundant but made minimal changes to 
the build system.

No, we're basically doing cp foo.a $LIBDIR/libfoo_dll.a At this point
LIB is set to libfoo_s.lib and LIBPREF is set to lib already. I did 
simplify a bit by using NAME.
I have also seemingly come across a bug (in pdksh or make? anyways some 
resource leaking) so am making sure cmd.exe invokes dllar.cmd.
Update patch enclosed including some redundant stuff from other patch I 
posted.
