I did, however, notice a problem with the usr.sbin/config/Makefile.
   in the SRCS line, config.c should be changed to config.y, and lang.c
   should be changed to lang.l.  Otherwise, among other things, "make
   clean" doesn't delete config.c or lang.c.

This is not correct.

CLEANFILES+=y.tab.h lang.c config.c y.tab.c

What you recommend will break other things, notably `make depend'.
