If you're using the same GNU Make 3.81 as me, it will greet you with some surprising messages: buggyMakefile:2: target `c99-pedantic' given more than once in the same rule. buggyMakefile:2: target `foobar' given more than once in the same rule. buggyMakefile:2: target `baz' given more than once in the same rule. make: `normal' is up to date. It's surprising because (a) there shouldn't be those "more than once" messages at all (the forward-slash makes them different targets), and (b) the messages are only produced for some words, not others. It depends on the words, not the order in the list. It is dependent on the characters in the words. If the words "normal" and "c89-pedantic" are changed to something else, even with the same length, they show up in the "more than once" errors. This bug was found with the "make-3.81-6" package distributed with 32-bit x86 Ubuntu 9.10 (Karmic Koala), which should be plain GNU Make 3.81.
