This appears to me to be a duplicate of bug #17752. I can no longer reproduce it in the latest CVS version of GNU make.

bash-3.00$ cat makefile

-include abc.def
-include abc.dep

%.do :
echo "$@: $^"
/bin/rm -f $.dep $.def

%.dep : %.def
echo "$*.do : $(DEF)" > $@

%.def :
echo "DEF := $*" > $@

makefile : ;
abc : ;
===========================================

Here's the o/p when we run with make 3.80

bash-3.00$ /sw/packages/make/3.80/bin/make abc.do
echo "DEF := abc" > abc.def
echo "abc.do : " > abc.dep
echo "abc.do: "
abc.do:
/bin/rm -f abc.dep abc.def

===========================================

When we run with 3.81

bash-3.00$ /sw/packages/make/3.81/bin/make abc.do
echo "DEF := abc" > abc.def
echo "abc.do : " > abc.dep
echo "DEF := abc" > abc.def
echo "DEF := abc" > abc.def
echo "DEF := abc" > abc.def

....
....
....

===========================================

AFAIK the issue here is make 3.81 is considering the .def file as intermediate file and deleting it after producing the .dep file so every time when it is re-reading the include statements it is not able to find the .def file and it is going into infinite loop.

when we add:

.SECONDARY : abc.def

or

.SECONDARY:

then make-3.81 does not delete abc.def (as part of cleaning up the intermediate files).

One more thing of interest here is if we change the order of includes to

-include abc.dep
-include abc.def

Then make 3.81 works fine !!.
