Is it really impossible to momentarily (and portably) flash the
header-line/ echo-area in the GNUstep build?

I heroically tried, but failed miserably right away. Building for
GNUstep (--with-ns) errors out in this compilation unit:

   gcc -std=gnu99 -c -Demacs -I. -I. -I../lib -I./../lib -D_REENTRANT -fPIC \
   -fno-strict-aliasing -I/usr/include/GNUstep -I/usr/local/include/GNUstep \
   -I/usr/include/alsa -pthread -I/usr/include/librsvg-2.0                  \
   -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include     \
   -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/cairo                       \
   -I/usr/include/libpng12 -I/usr/include/pixman-1 -I/usr/include/freetype2 \
   -I/usr/include/libxml2 -I/usr/include/dbus-1.0                           \
   -I/usr/lib/x86_64-linux-gnu/dbus-1.0/include -MMD -MF deps/nsterm.d -MP  \
   -I/usr/include/p11-kit-1 -g3 -O2 -fobjc-exceptions -fgnu-runtime         \
   -Wno-import -fconstant-string-class=NSConstantString                     \
   -DGNUSTEP_BASE_LIBRARY=1 -DGNU_GUI_LIBRARY=1 -DGNU_RUNTIME=1 -DGSWARN    \
   -DGSDIAGNOSE nsterm.m

Many errors, at least in today's and recent git clonings

   nsterm.m:6075:1: error: trying to encode non-integer type as a
   bitfield

Besides the reasonably complete toolkit I use to compile for GTK, I'm on
debian wheezy and installed "gnustep-core-devel", version 7.7. Configure
ran fine.

I wonder if these are known pitfalls and if you can point me in the
right direction 

I vaguely remember --with-ns building OK on OSX, but haven't tried
recently.

Thanks,
