A file called gdbsrc.el used to do something like this in XEmacs and I
considered it for a while.  I think it's the wrong approcah because generally
in a debug session you end up wanting to edit your code.

This way, as you say, source-guding-mode is evaluated for all files.
gdb-find-file-hook is also evaluated for all files but it doesn't do
anything if gud-minor-mode is not 'gdba or 'gdbmi.

Since you probably want to set source-guding-mode for existing buffers too
it may be best to advise gdb-init-buffer.  This function only gets called
for GDB related buffers.
