+ /* 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'
+ VOLATILE `volatile' `'
+ SIGNED `signed' `'
+ PTRCONST `void *const' `char *'
+ ANSI_PROTOTYPES 1 not defined
+
+ CONST is also defined, but is obsolete. Just use const.
+
+ obsolete -- 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'.
+
+ obsolete -- DEFUN_VOID (name)
+
+ Defines a function NAME, which takes no arguments.
+
+ obsolete -- EXFUN (name, (prototype)) -- obsolete.
+
+ Replaced by PARAMS. Do not use; will disappear someday soon.
+ Was used in external function declarations.
+ In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
+ parentheses). In traditional C it is `NAME()'.
+ For a function that takes no arguments, PROTOTYPE should be `(void)'.
+
+ obsolete -- PROTO (type, name, (prototype) -- obsolete.
+
+ This one has also been replaced by PARAMS. Do not use.
+
+ PARAMS ((args))
+
+ We could use the EXFUN macro to handle prototype declarations, but
+ the name is misleading and the result is ugly. So we just define a
+ simple macro to handle the parameter lists, as in:
+
+ static int foo PARAMS ((int, char));
+
+ This produces: `static int foo();' or `static int foo (int, char);'
+
+ EXFUN would have done it like this:
+
+ static int EXFUN (foo, (int, char));
+
+ but the function is not external...and it's hard to visually parse
+ the function name out of the mess. EXFUN should be considered
+ obsolete; new code should be written to use PARAMS.
+
+ DOTS is also obsolete.
+
+ Examples:
+
+ extern int printf PARAMS ((const char *format, ...));
