--- Comment #7 from Mike Stump <mikestump at comcast dot net> 2011-03-07 18:16:13 UTC --- Ok, you can look for strlen (s) == IDENTIFIER_LENGTH (x) in either the darwin.[ch] files, or, failing one there, in the backend files... I know I've seen one before, just can't recall where exactly. In theory, the two should be virtually identical, or one of them is wrong.
