IIRC, last time this was discussed, Per Bothner suggested to use the
current directory recorded in the debug info to convert a relative or
semi-relative file name into an absolute one.

Unless I'm mistaken, your patch doesn't do that.  Any particular
reason?  Per's suggestion did seem like the best solution to this.

I think this needs to be tested with as many debug infor formats as
possible.  What format did you use? DWARF2?
