It sounds to me that what you want to do, is for some people, not
check the  VB dependancies. If you don't check the dependancies, you
don't try to recompile  them. Here's one way to do that...2 batch
files, one for VB users, one for the others.

m.bat
 - - - -
@set FILE=%1
@set RES=%1
@set USEVB=NO
::change to yes for the VB users
make  -fm.mak

m.mak
 - - - -
LIBPATH = whatever 
INCLUDEPATH = whatever 
CC   = whatever
TLINK = whatever
RC    = whatever
VB = whatever

OBJ = list of obj files less the vb.obj
VBOBJ = list of the vb.obj

..c.obj:
      $(CC)  $&.c

..cpp.obj:
      $(CC)  $&.cpp

..rc.res:
      $(RC) $&

!if $(USEVB)==NO
VBOBJ = #Nothing
..SUFFIXES: .exe .lib .obj .asm .c .res .rc
#You could also throw in a do-nothing
#.vb.obj:
#   report need for VB rebuild
#  
!else
..vb.obj:
    $(VB) whatever

..SUFFIXES: .exe .lib .obj .asm .c .res .rc .vb
!endif

#		*Explicit Rules*
$(FILE).exe: $(FILE).obj $(RES).res $(OBJ) $(VBOBJ)
   $(TLINK) etc.


I also like the use of LIB files.
$(FILE).exe: $(FILE).obj $(RES).res $(LIBS)
It will just see that the lib is new or old, no sub-dependancy checks,
or trying to rebuild the lib.
The lib would have it's own make.
