bug#7380: 23.2; Dead keys misinterpreted in gtk emacs

[Ian D. Leroux <idleroux@fastmail.fm>]

Under X11 with the us_intl keyboard, dead keys are not correctly
combined with the following characters.  For instance <dead-acute> e,
which ought to give é, instead produces the message "<dead-acute> is
undefined" followed by an undecorated e.  The problem is specific to
emacs: all other applications in the same X11 session (Firefox, xterm,
urxvt, miscellaneous gtk apps like exfalso) accept accented input
typed with dead keys without special customization.  This is a
plain-vanilla install of emacs under pkgsrc.  The auto-collected data
reported below were generated by M-x report-emacs-bug from an emacs -Q
instance displaying this behaviour.

Workarounds: I can run emacs in a terminal, allowing xterm or urxvt to
handle keyboard input.  This gives me consistent keyboard behaviour at
the price of the graphical comforts of gtk emacs.  I can also activate
iso-transl and have emacs handle the composition of characters from
dead keys by its own internal mechanism, independent of X11, but then
I get a subtly different keyboard layout in emacs relative to other
software on the system.

Thank you for any insights and assistance you may be able to supply,

Ian Leroux
