That's the way GCC does it for libstdc++; the Python pretty-printer
macros are shipped with GCC and installed as part of installing the
compiler (IIRC), and it's up to the person putting together their
environment to DTRT, which usually involves adding a source line to
their .gdbinit file or whatever.
