Wow, that's pretty cool!  So your patches are actually in GDB now, are
they?

Notwithstanding, it looks like my conclusion that we don't need
GDB_INTERFACE and GDB_INTERFACE_INIT in guile.c is still correct - can
you confirm that?

(In other words, instead of using some kind of registration API, I
guess that GDB either links to libguile, or looks up the gdb_*
functions that it needs dynamically, or has an independent copy of the
libguile code that it needs to do printing.  Is that right?)
