`M-x recompile' is your friend.

Perhaps the Desktop library (documented in the "Saving Emacs Sessions"
node of the Emacs manual) will do the trick, once compile-command has
been added to desktop-globals-to-save.

Desktop probably does more than you want, though, so maybe you'll want
to set desktop-buffers-not-to-save and/or desktop-files-not-to-save to
".*".

Or you could roll your own kill-emacs-hook that writes
(setq compile-command "...")
to ~/compile-command.el, and have ~/.emacs automatically load
"~/compile-command".
