freebsd stable - Mar 2005 - gdb missing add-shared-symbol-files. why?

Hi,

played with dmalloc and the docu says to do the following in gdb:
(gdb) sharedlibrary
(gdb) add-shared-symbol-files
This command is not available in this configuration of GDB.
(gdb) break dmalloc_error

Why is this command not available? The code in question is at
/usr/src/contrib/gdb/gdb/symfile.c:1760

static void
add_shared_symbol_files_command (char *args, int from_tty)
{
#ifdef ADD_SHARED_SYMBOL_FILES
  ADD_SHARED_SYMBOL_FILES (args, from_tty);
#else
  error ("This command is not available in this configuration of
GDB.");
#endif
}

I grepped the whole src-tree for ADD_SHARED_SYMBOL_FILES. No luck.
What's up? (Note, devel/gdb6 has the same "problem").

I believe gdb automatically loads dynamic libraries linked against a
binary when that binary is debugged. So that command many not have any
affect on FreeBSD.
