Subject: Compile failure due to Xaw3d include file issues

[Resending, since my first message didn't appear on the list for some reason.]

Hi,
not entirely sure if this is really an Emacs bug (or if X.Org is to
blame):

Emacs 22.0.97 compilation fails on a system where:
- - Xaw3d is installed,
- - libXaw is not installed. 

Configure defines HAVE_XAW3D=1 in src/config.h, but in spite of this
include files are expected to be in /usr/include/X11/Xaw
(e.g., Paned.h) that don't exist there (since libX11 is not
installed).

Xaw3d installs its own include files, but they are in
/usr/include/X11/Xaw3d (there is a Paned.h, too).

On the other hand, if I install libXaw on the system and compile Emacs
(the include files are there and compilation succeeds now), ldd or
scanelf show that the libXaw _library_ is not needed:

   $ scanelf -n src/emacs
    TYPE   NEEDED FILE 
   ET_EXEC libXaw3d.so.8,libXmu.so.6,libXt.so.6,libSM.so.6,libICE.so.6,libXext.so.6,libX11.so.6,libncurses.so.5,libm.so.6,libc.so.6 src/emacs 

So a possible workaround is to install in addition libX11 during build
time, while at run time it is not required. This doesn't look like a
clean solution, however.

(If I do "make -k bootstrap", there is the same issue for src/xmenu.c
and src/xfns.c.)
