Ignore this for now.  I thought file->src_root was the name of the INF
file, but it's just the directory where the inf file exists.  Is there
any way I can find out the filename of the INF file using the pointer
to the inf_file?  I don't know if there are objections to adding a
filename field to the inf_file structure, but that is an option.
