No, it's `full', because the compile directory was "/foo/bar".

"My compiler" in this case identifies itself as
gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3
I'd be surprised if this version omits comp_dir, but if someone tells

Then maybe "as-recorded"? Meaning that this is how the compiler
recorded the file name in the debug info?
