Actually, it's also meant to be used directly by GDB.  Normally, GDB
should try to display SCM values on its own (using its own copy of
`tags.h' and the corresponding printing procedures) and resort to
calling `gdb_print ()' when it doesn't know how to display a value.

In practice, GDB currently only supports the latter, which makes it
not-so-useful (the same result can be achieved with trivial GDB macros).
See http://sourceware.org/ml/gdb-patches/2007-07/msg00231.html .

Thanks,
Ludo'.
