69 [...] The X11 include files that Dec distributes with Ultrix
70 are bogus.
71
72 When __STDC__ is defined (which is true with gcc), the X11 include files
73 try to define prototypes. The prototypes however use types which haven't
74 been defined yet, and thus we get syntax/parse errors.
75
76 You can not fix this by changing the include files, because the prototypes
77 create circular dependencies, in particular Xutil.h depends on types defined
78 in Xlib.h, and Xlib.h depends on types defined in Xutil.h. So, no matter
79 which order you try to include them in, it will still fail.
80
81 Compiling with -DNeedFunctionPrototypes=0 will solve the problem by
82 directly inhibiting the bad prototypes. This could perhaps just be put in
83 an a Ultrix configuration file.
84
85 Using the MIT X11 distribution instead of the one provided by Dec will
86 also solve the problem, but I doubt you can convince everyone to do this. */
87
88 /* Addendum: the MIT X11 distribution neglects to define certain symbols
89 when NeedFunctionPrototypes is 0, but still tries to use them when
90 NeedVarargsPrototypes is 1 (which is its default value). So if we're
91 going to disable non-variadic prototypes, we also need to disable
92 variadic prototypes. --kwzh@gnu.ai.mit.edu */
