bsd.lib.mk question

[David Holland <dholland-tech%netbsd.org@localhost>]

Does anyone know why bsd.lib.mk contains the following logic?

   _YLSRCS=        ${SRCS:M*.[ly]:C/\..$/.c/} ${YHEADER:D${SRCS:M*.y:.y=.h}}
      :
   DPSRCS+=        ${_YLSRCS}
      :
   ${STOBJS} ${POBJS} ${GOBJS} ${SOBJS} ${LOBJS}: ${DPSRCS}

It appears that this forces a complete recompile any time a .l or .y
file is touched, which seems entirely wrong.
