/* ANSI and traditional C compatibility macros
20
 
21
   ANSI C is assumed if __STDC__ is #defined.
22
 
23
   Macro        ANSI C definition       Traditional C definition
24
   -----        ---- - ----------       ----------- - ----------
25
   PTR          `void *'                `char *'
26
   LONG_DOUBLE  `long double'           `double'
27
   VOLATILE     `volatile'              `'
28
   SIGNED       `signed'                `'
29
   PTRCONST     `void *const'           `char *'
30
   ANSI_PROTOTYPES  1                   not defined
31
 
32
   CONST is also defined, but is obsolete.  Just use const.
33
 
34
   DEFUN (name, arglist, args)
35
 
36
        Defines function NAME.
37
 
38
        ARGLIST lists the arguments, separated by commas and enclosed in
39
        parentheses.  ARGLIST becomes the argument list in traditional C.
40
 
41
        ARGS list the arguments with their types.  It becomes a prototype in
42
        ANSI C, and the type declarations in traditional C.  Arguments should
43
        be separated with `AND'.  For functions with a variable number of
44
        arguments, the last thing listed should be `DOTS'.
45
 
46
   DEFUN_VOID (name)
47
 
48
        Defines a function NAME, which takes no arguments.
49
 
50
   obsolete --     EXFUN (name, (prototype))    -- obsolete.
51
 
52
        Replaced by PARAMS.  Do not use; will disappear someday soon.
53
        Was used in external function declarations.
54
        In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
55
        parentheses).  In traditional C it is `NAME()'.
56
        For a function that takes no arguments, PROTOTYPE should be `(void)'.
57
 
58
    PARAMS ((args))
59
 
60
        We could use the EXFUN macro to handle prototype declarations, but
61
        the name is misleading and the result is ugly.  So we just define a
62
        simple macro to handle the parameter lists, as in:
63
 
64
              static int foo PARAMS ((int, char));
65
 
66
        This produces:  `static int foo();' or `static int foo (int, char);'
67
 
68
        EXFUN would have done it like this:
69
 
70
              static int EXFUN (foo, (int, char));
71
 
72
        but the function is not external...and it's hard to visually parse
73
        the function name out of the mess.   EXFUN should be considered
74
        obsolete; new code should be written to use PARAMS.
75
 
76
    For example:
77
        extern int printf PARAMS ((CONST char *format DOTS));
78
        int DEFUN(fprintf, (stream, format),
79
                  FILE *stream AND CONST char *format DOTS) { ... }
80
        void DEFUN_VOID(abort) { ... }
