Emacs 22.1 compiler warnings if configured --with-x-toolkit=no

[Ulrich Mueller]

During compilation of Emacs 22.1 (and 21.4, too) the following
warnings appear:

   i686-pc-linux-gnu-gcc -c  -D_BSD_SOURCE     -D_BSD_SOURCE
   -march=pentium-m -O2 -pipe -DEMACS_BITMAP_FILES -I../src
   -I/var/tmp/portage/app-editors/emacs-22.1/work/emacs-22.1/oldXMenu
   -I/var/tmp/portage/app-editors/emacs-22.1/work/emacs-22.1/oldXMenu/../src
   ChgPane.c
   ChgPane.c: In function 'XMenuChangePane':
   ChgPane.c:46: warning: incompatible implicit declaration of built-in
   function 'strlen'

   i686-pc-linux-gnu-gcc -c  -D_BSD_SOURCE     -D_BSD_SOURCE
   -march=pentium-m -O2 -pipe -DEMACS_BITMAP_FILES -I../src
   -I/var/tmp/portage/app-editors/emacs-22.1/work/emacs-22.1/oldXMenu
   -I/var/tmp/portage/app-editors/emacs-22.1/work/emacs-22.1/oldXMenu/../src
   ChgSel.c
   ChgSel.c: In function 'XMenuChangeSelection':
   ChgSel.c:62: warning: incompatible implicit declaration of built-in
   function 'strlen'

Emacs was configured as follows:

   configure  '--prefix=/usr' '--host=i686-pc-linux-gnu'
   '--mandir=/usr/share/man' '--infodir=/usr/share/info'
   '--datadir=/usr/share' '--sysconfdir=/etc' '--localstatedir=/var/lib'
   '--program-suffix=-emacs-22' '--infodir=/usr/share/info/emacs-22'
   '--without-carbon' '--with-sound' '--with-x' '--with-xpm'
   '--without-toolkit-scroll-bars' '--with-jpeg' '--with-tiff'
   '--with-gif' '--with-png' '--with-x-toolkit=no' '--without-gtk'
   '--build=i686-pc-linux-gnu' 'build_alias=i686-pc-linux-gnu'
   'host_alias=i686-pc-linux-gnu' 'CFLAGS=-march=pentium-m -O2 -pipe'

This patch should fix the problem:
