The problem is likely with the empty tmp.a. Why do you need such an 
empty archive?

In any case, the right way to create an empty archive is to "ar r foo.a" 
(without any file arguments). This gives you an empty archive with just 
an "ar" header (which is really just the characters "!<arch>\n").

In fact, when I try your experiment with a zero-length foo.a, I get a 
completely different message (with cygwin 1.3.12-4 and ar 2.12.90 
20020706: "ar: foo.a: File format not recognized".

Unless your "empty" file is somehow different - I just did a "touch 
foo.a" to create my empty file.
