Hi,
Recently, we upgraded from Make version 3.76.1 to version 3.79.1, and now I'm having a
problem doing a "make depend" with my Makefile. The problem is that Make 3.79.1 loops
indefinitely. In my opinion this is a bug, because Make 3.79.1 "forgets" to out-date
the .depend file it just created. Thus it is recreated over and over again (well, not
in this demo, because make is doing its job so fast that .depend turns out to be
up-to-date, but when you have a larger number of source and header files it *will*
loop indefinitely).
Comparing the line "Re-executing:" in the log files for Make 3.76.1 and 3.79.1 shows
this:
make_3-76-1.log:Re-executing: make -d depend -o.depend -oMakefile
make_3-79-1.log:Re-executing: /usr/bin/make_3_79 -d depend
Hardware: PC Pentium-III (800 MHz)
OS: SuSE Linux 7.0 (i386) - Kernel 2.2.16 (7)

P.S.: For your convenience, I added the Makefile below (it is also present in the
attached compressed tar file)
>>>>>>>>>>>>>>>>
EXES = main
.PHONY : default all depend
default : $(firstword $(EXES))
all : $(EXES)
depend :
CXX = g++

DEPEND = .depend
PRGS = $(addsuffix .cc, $(EXES))
SRCS = $(filter-out $(PRGS), $(wildcard *.cc))
LIB = libmylib.a
$(EXES): $(LIB)
$(LIB): $(SRCS:%.cc=$(LIB)(%.o))
$(DEPEND): depend
@echo "Updating dependencies ..."
