the problem is not solved, merely one of the manifestation is eliminated.
actual solution requires stating all the dependencies.

if your list of sources and/or targets is dynamic, consider using mk include:
<| GEN_DEPS
where `GEN_DEPS' is your script generating deps in form TARGET: PREREQUISITE

The following mkfile does what I need/expect without explicit dependencies.

# Makefile for Plan 9

DYNACE_PATH = ../..

BINDIR = $DYNACE_PATH/bin

CFILES = main.c

OBJS = ${CFILES:%.c=%.$O} ${CLASSES:%.d=%.$O}

CFLAGS = -DPLAN9 -I$INCDIR -p

C_CLASSES = ${CLASSES:%.d=%.c}
