+/* ANSI and traditional C compatibility macros
+
+ ANSI C is assumed if __STDC__ is #defined.
+
+ Macro ANSI C definition Traditional C definition
+ ----- ---- - ---------- ----------- - ----------
+ PTR `void *' `char *'
+ LONG_DOUBLE `long double' `double'
+ CONST `const' `'
+ VOLATILE `volatile' `'
+ SIGNED `signed' `'
+ PTRCONST `void *const' `char *'
+
+ DEFUN(name, arglist, args)
+
+ Defines function NAME.
+
+ ARGLIST lists the arguments, separated by commas and enclosed in
+ parentheses. ARGLIST becomes the argument list in traditional C.
+
+ ARGS list the arguments with their types. It becomes a prototype in
+ ANSI C, and the type declarations in traditional C. Arguments should
+ be separated with `AND'. For functions with a variable number of
+ arguments, the last thing listed should be `DOTS'.
+
+ DEFUN_VOID(name)
+
+ Defines a function NAME, which takes no arguments.
+
+ EXFUN(name, prototype)
+
+ Is used in an external function declaration.
+ In ANSI C it is `NAMEPROTOTYPE' (so PROTOTYPE should be enclosed in
+ parentheses). In traditional C it is `NAME()'.
+ For a function that takes no arguments, PROTOTYPE should be `(NOARGS)'.
+
+ For example:
+ extern int EXFUN(printf, (CONST char *format DOTS));
+ int DEFUN(fprintf, (stream, format),
+ FILE *stream AND CONST char *format DOTS) { ... }
+ void DEFUN_VOID(abort) { ... }
