This is asically issue 44902 but working on issue 61969 showed some interesting
new aspects of the issue.

The folowing makefile
- - - inc_circ.mk - - -
SHELL*:=/bin/sh 
SHELLFLAGS*:=-ce

TARGET=mytarget

%.dpcc : %.cpp
        @echo making: $@
#       @+echo $@ :  > $@
        @+echo AA=123 > $@

.INCLUDE : $(TARGET).dpcc

ALL : $(TARGET).dpcc
- - - inc_circ.mk - - -

shows the following output:

$ rm -f mytarget.dpcc ; dmake/dmake.exe -r -f inc_circ.mk
making: mytarget.dpcc
dmake:  inc_circ.mk:  line 13:  Error: -- Detected circular dependency in graph
at [mytarget.dpcc]

But if one moves the comment from line 8 to 9 the error vanishes.

Or adding an empty target rule
mytarget :
after the .INCLUDE also helps.

It's not a circular dependency, the problem is that F_VISITED and F_USED both
have the same value but are used in different contexts. Making the include
sets F_VISITED and thus creates the apparent circular dependency in the F_USED
check.

Having the included file as a target in an additional rule resets the F_USED
setting. A lot of the *.dp* rules are "self healing" as they include something
like:
        @+echo $@ : <something> >> $@
