I don't really understand the question.  How would the user know when
to use any other option?  If they read the documentation and
understand the issues, they will know.

No.  We were talking about finding sources given file names recorded
in the debug info.  Finding the program given the command-line
arguments is not the same problem, and I don't thing GDB uses any of
these macros to do that, or needs to.
