Your interpretation seems satisfying. But this hangs *also* if there is a Makefile, and an aux target declared in it, but without a .PHONY directive. I simplified the test case on purpose, but apparently too much. Ok, ok, apart from reading the cygwin FAQ, I should probably take some extra courses in computer science, and go 'info make' from time to time. All this I did. The correct Makefile should say: aux: @echo Making aux .PHONY: aux This works fine (and is 'clean' make compliant etc etc). Declaring aux as a phony avoids the call to stat (which seems natural ;), and thus prevents cygwin from hanging on it. Again, this worked *before*. You tell me it does not any longer. Fine. This is just yet another system discrepancy. Too bad, I'll live with it. For the record, I straced the same [simple] test case on a linux, here is the trace (notice how its readable): stat("RCS", 0xbfffe30c) = -1 ENOENT (No such file or directory) stat("SCCS", 0xbfffe30c) = -1 ENOENT (No such file or directory) stat("GNUmakefile", 0xbfffe30c) = -1 ENOENT (No such file or directory) stat("makefile", 0xbfffe30c) = -1 ENOENT (No such file or directory) stat("Makefile", 0xbfffe30c) = -1 ENOENT (No such file or directory) brk(0x806f000) = 0x806f000 stat("aux", 0xbfffe274) = -1 ENOENT (No such file or directory) write(2, "make: *** ", 10make: *** ) = 10 write(2, "No rule to make target `aux\'", 28No rule to make target `aux') = 28 write(2, ".
