#define __STDC_C78

Does not comply with C89 or later standard! Most likely complies with 1978 K&R C standard (informally known as C78)

CAT

#define CAT	(		a,
			b )

Value:

a##b

Preprocessor Name catenation of a and b (use of XCAT is highly recommended for any need)

Warning

No nesting possible, use XCAT instead (unless there is a good reason not to use XCAT)

STR

#define STR

(

s

)

Value:

#s

Stringify s expression.

XCAT

#define XCAT	(		a,
			b )

Value:

CAT(a, b)

Preprocessor Name catenation of a and b (nesting possibility)

XSTR

#define XSTR

(

s

)

Value:

STR(s)

Stringify the result of s expression expansion (stringification of a macro expansion)
