| 97 | [...] The X11 include files that Dec distributes with Ultrix | ||
| 98 | are bogus. | ||
| 99 | |||
| 100 | When __STDC__ is defined (which is true with gcc), the X11 include files | ||
| 101 | try to define prototypes. The prototypes however use types which haven't | ||
| 102 | been defined yet, and thus we get syntax/parse errors. | ||
| 103 | |||
| 104 | You can not fix this by changing the include files, because the prototypes | ||
| 105 | create circular dependencies, in particular Xutil.h depends on types defined | ||
| 106 | in Xlib.h, and Xlib.h depends on types defined in Xutil.h. So, no matter | ||
| 107 | which order you try to include them in, it will still fail. | ||
| 108 | |||
| 109 | Compiling with -DNeedFunctionPrototypes=0 will solve the problem by | ||
| 110 | directly inhibiting the bad prototypes. This could perhaps just be put in | ||
| 111 | an a Ultrix configuration file. | ||
| 112 | |||
| 113 | Using the MIT X11 distribution instead of the one provided by Dec will | ||
| 114 | also solve the problem, but I doubt you can convince everyone to do this. */ | ||
| 115 | /* Addendum: the MIT X11 distribution neglects to define certain symbols | ||
| 116 | when NeedFunctionPrototypes is 0, but still tries to use them when | ||
| 117 | NeedVarargsPrototypes is 1 (which is its default value). So if we're | ||
| 118 | going to disable non-variadic prototypes, we also need to disable | ||
| 119 | variadic prototypes. --kwzh@gnu.ai.mit.edu */ | ||
