* m/pmax.h (C_SWITCH_X_MACHINE): Set this to

	"-DNeedFunctionPrototypes=0", to avoid lossage in DEC X11 header
	files.
	* ymakefile (really-oldXMenu): Pass C_SWITCH_X_MACHINE to the
	oldXMenu make.

[...] The X11 include files that Dec distributes with Ultrix
are bogus.
When __STDC__ is defined (which is true with gcc), the X11 include files
try to define prototypes. The prototypes however use types which haven't
been defined yet, and thus we get syntax/parse errors.
You can not fix this by changing the include files, because the prototypes
create circular dependencies, in particular Xutil.h depends on types defined
in Xlib.h, and Xlib.h depends on types defined in Xutil.h. So, no matter
which order you try to include them in, it will still fail.
Compiling with -DNeedFunctionPrototypes=0 will solve the problem by
directly inhibiting the bad prototypes. This could perhaps just be put in
an a Ultrix configuration file.
Using the MIT X11 distribution instead of the one provided by Dec will
also solve the problem, but I doubt you can convince everyone to do this. */
