Just for the record: firefox's download manager performs exactly this test to decide whether you can 'open with' a file (pretty silly because the test is done on the freshly downloaded file in the temp dir which never has an x-bit set). But I was hit by this effect on my system which is - surprise surprise - Linux :-) Ok, it's a pretty old one with a 2.0 kernel and libc 5. But nevertheless, access(2) is not the right function to portably test the x-bit.
