Dear GNU team,
I just want to report a strange behaviour I met, using gmake version
3.78. Everything worked fine with version 3.77. You will find in the
attached tar file an example to produce the problem.
Configuration :
---------------
First of all, here it is my configuration. I run Redhat Linux 6.1 :
$ uname -a
Linux dclin01 2.2.12-20 #1 Mon Sep 27 10:40:35 EDT 1999 i686 unknown
$ /usr/local/bin/gmake --version
GNU Make version 3.78.1, by Richard Stallman and Roland McGrath.
Built for i686-pc-linux-gnu

The "config.h" is provided in the tar file.
How to produce the problem :
----------------------------
$ cat Makefile
CC = gcc -Wall
OBJ = lib.o
all: test
lib.o: lib.c string.inc
test: test.o lib.a($(OBJ))
$(CC) -o test test.o lib.a
clean:
rm *.o *.a test
.INTERMEDIATE: $(OBJ)
Proceed like this :
$ gmake
gcc -Wall -c -o test.o test.c
gcc -Wall -c -o lib.o lib.c
ar rv lib.a lib.o
a - lib.o
gcc -Wall -o test test.o lib.a
rm lib.o
$ ./test
Hello World
$ touch string.inc
$ gmake # <-- Should recompile lib.o, generate
gmake: Nothing to be done for `all'. # lib.a, then compile test
Description of the problem :
----------------------------
It seems that the problem is linked with the Archive members facility.
For some reasons, make does not stat the string.inc file.
$ touch string.inc
$ strace gmake
...
stat("RCS", 0xbfffd8cc) = -1 ENOENT (No such file or directory)
stat("SCCS", 0xbfffd8cc) = -1 ENOENT (No such file or directory)

_llseek(3, 100, [100], SEEK_SET) = 0
read(3, "lib.o/ 955037436 3194"..., 60) = 60
close(3) = 0
open("s.lib.a", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("s.", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)

stat("lib.c", {st_mode=S_IFREG|0644, st_size=111, ...}) = 0
fstat(1, {st_mode=S_IFREG|0644, st_size=4852, ...}) = 0
mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40013000
write(1, "gmake: Nothing to be done for `a"..., 37gmake: Nothing to be done for `all'.
) = 37
