(This should either be put in a 'README.sun' file, or done
automatically in fixincludes.)

Under SunOS 3.5 the files
<sunwindow/win_cursor.h>
<suntool/icon.h>    and 
<pixrect/memvar.h>
reference the macro 'CAT' which is defined in <pixrect/memvar.h>.  To
work correctly under ANSI C, memvar.h should be changed as follows:

cd /usr/include/pixrect/
diff -c memvar.h /usr/local/lib/gcc-include/pixrect/memvar.h
*** memvar.h	Mon Sep 15 16:55:23 1986
--- /usr/local/lib/gcc-include/pixrect/memvar.h	Tue Dec 13 14:51:50 1988
