Dear GNU Make developers,
I am using
$ make --version
GNU Make 3.81
Copyright (C) 2006 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.
There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A

This program built for i686-redhat-linux-gnu
An infinite loop occurs with the makefile
$ cat loop-double.make
testLib :: testLib.so
testLib.so : X.o
touch $@
testLib :: testLibinstall
testLibinstall : /tmp/testLib.so
/tmp/testLib.so : testLib.so
cp $< $@
dependencies.make : X.c
rm -f $@
echo X_c = X.c >> $@
-include dependencies.make
X.o : $(X_c)
cp $< $@
.DEFAULT :
@echo "Warning: $@: No rule for such target" >&2
if test -n "$(MAKE_RESTARTS)" && test "$(MAKE_RESTARTS)" -gt 0;
then\
exit 1;\
else\
exit 0; fi

Make fails (as it should) to rebuild the first double-colon rule target
as X.c does NOT exist
but still tries to consider apparently the second double-colon target.
$ make -f loop-double.make -d
...
Considering target file `testLib'.
Recently tried and failed to update file `testLib'.
Pruning file `testLib'.
Considering target file `testLib'.
...
Probably, Make should fail in this situation?
Thank you very much,
Grigory
