Well, I haven't had enough time to investigate this more, however, I did
find some odd results with the example I came up with. For example, if
I do 'info sources' before the dir command is applied, GDB spits out the
relative path. However, if I do the dir command, and then do 'info
sources', then GDB spits out the absolute path.

Once GDB has the absolute path, if I then do 'list uut.h:1', GDB can
still not find the file. If I do 'list ../include/uut.h:1',
then I get an Internal GDB error. Do you get these same results?

If so, find_and_open_source is finding the fullname, even though things
are still not working properly. Hopefully I'll have more time to look
into this today.
