This is what I get, which passes

file should be the path that gdb has always produced. The relative path
to the source file given from where it was compiled. Its basically what
you should get when you do 'info sources'.

fullname should be the absolute path to the source file.
I only tested it for starting with a / and ending with basics.c because
that seemed to be a good and easy way to ensure the file was absolute.

I think your suggestion of what file should match is a good one.
The fullname match should probably not change. Since ${srcfilepath} is not
guaranteed to be the absolute path to the source file.
