No idea what "directly" means here.  John suggested using
"gdb --args emacs <args to Emacs>".  I put this in a Windows
shortcut and tried it:

 <path-to>\gdb.exe --args emacs --debug-init <my-dir>

Where <path-to> is the path to the (old) binary I have, and
<my-dir> is a directory I want to dired as my first window.

(Normally I use "<path-to>\runemacs.exe --debug-init <my-dir>".)

No.  I've never used Emacs 20.7 with gdb.  It was a binary I
got in 2010 to try to debug something you asked about, and
using a dev snapshot at that time (would that have been an
Emacs 23 snapshot?).  I thought perhaps I got the binary from
you or from somewhere you pointed me to.

OK, thanks.  I tried using that and got the attached error.
What's the easiest way to remedy this?  (Why doesn't the gdb
binary include everything it needs?)  Thx.
