customizing emacs at compile time (or with dump-emacs?)

customizing emacs at compile time (or with dump-emacs?)

[Joe Corneli]

I was reading in the GNU Emacs Lisp Reference Manual about ways to
change the Emacs binary.  My .emacs has gotten fairly big, and I
think it would be nice to put together a new version of emacs that
incorporates my changes but that doesn't take a long time to load.
Would 

% emacs -batch -f (dump-emacs my-emacs /full/path/to/emacs/)

do this for me?

Run Emacs under a debugger and when it gets SIGSEGV, look around to
see what went wrong.  The file etc/DEBUG in the Emacs distro has
several hints on debugging Emacs.

Replace $MYEMACS with "gdb $MYEMACS --args", that will run Emacs
under GDB.
