NEW failure in building Emacs 23.0.50 on Cygwin

[Angelo Graziosi]

It looks that this change:

------------------------------------------------------------------
2007-09-07  Stefan Monnier  <address@hidden>

        * window.c (Vsplit_window_preferred_function): New var.
        (Fdisplay_buffer): Use it.
        (syms_of_window): Export, and initialize it.

------------------------------------------------------------------


breaks the bootstrap of Emacs-CVS on Cygwin (at least):
------------------------------------------------------------------
...
gcc -c  -Demacs -DHAVE_CONFIG_H -DUSE_LUCID  -I. -I/tmp/emacs/src
-I/usr/X11R6/include   -g -O2 -Wno-pointer-sign  /tmp/emacs/src/window.c
/tmp/emacs/src/window.c: In function 'Fdisplay_buffer':
/tmp/emacs/src/window.c:3731: error: address of register variable 'buffer'
requested
make[2]: *** [window.o] Error 1
make[2]: Leaving directory `/tmp/emacs/build/src'
make[1]: *** [bootstrap-build] Error 2
make[1]: Leaving directory `/tmp/emacs/build'
make: *** [bootstrap] Error 2
------------------------------------------------------------------


The last check-out I did less than 24 hours ago (with the 'famous' patch
applied to term.c) build fine.



Cheers,

   Angelo.
