This test is working correctly in the latest CVS version.

I took a look at this.  It seems to belong to a class of bugs introduced in 3.81 by some (unintentional; at least I didn't intentionally do it) change related to handling of directory separators (/).  In previous versions of make I believe there was some effort to canonicalize directories by removing trailing slashes and perhaps even leading "./" chars.  Apparently that is no longer working the same way.

If I change your makefile to remove the trailing slashes from the variables so the order-only prereqs don't contain trailing slashes (and add them in as appropriate so the result is the same), then it works as expected in both 3.80 and 3.81.

I have been establishing a build environment and infrastructure for a project I am working on.

In the course of doing so, I have found some inexplicable behavior in make 3.81 when compiling and generating archive libraries in a pristine build tree. The issue manifests itself on both Mac OS X / Darwin on i686 and Ubuntu Desktop 7.10 on i686.

The behavior is that make creates the necessary object, depend and results directories based on order-only prerequisites in my implicit rules, correctly compiles the first source file into an object for the archive library, but then regards all other objects as complete and then tries to archive the library with non-existent and un-built objects:

% make
mkdir -p .depends
mkdir -p .objects
gcc -g -O1 -MD -MP -MF .depends/a.d -c -o .objects/a.o a.c
mkdir -p .results
ar -cr .results/libalphabet.a .objects/a.o .objects/b.o .objects/c.o .objects/d.o .objects/e.o .objects/f.o .objects/g.o .objects/h.o
ar: .objects/b.o: No such file or directory
ar: .objects/c.o: No such file or directory
ar: .objects/d.o: No such file or directory
ar: .objects/e.o: No such file or directory
ar: .objects/f.o: No such file or directory
ar: .objects/g.o: No such file or directory
ar: .objects/h.o: No such file or directory
make: * [.results/libalphabet.a] Error 1

If I then run make again, the order-only prerequisites having been already satisfied this time around, things work as expected:

% make
gcc -g -O1 -MD -MP -MF .depends/b.d -c -o .objects/b.o b.c
gcc -g -O1 -MD -MP -MF .depends/c.d -c -o .objects/c.o c.c
gcc -g -O1 -MD -MP -MF .depends/d.d -c -o .objects/d.o d.c
gcc -g -O1 -MD -MP -MF .depends/e.d -c -o .objects/e.o e.c
gcc -g -O1 -MD -MP -MF .depends/f.d -c -o .objects/f.o f.c
gcc -g -O1 -MD -MP -MF .depends/g.d -c -o .objects/g.o g.c
gcc -g -O1 -MD -MP -MF .depends/h.d -c -o .objects/h.o h.c
ar -cr .results/libalphabet.a .objects/b.o .objects/c.o .objects/d.o .objects/e.o .objects/f.o .objects/g.o .objects/h.o
ranlib .results/libalphabet.a

It works successfully under 3.80 but fails under 3.81:
