QA·C Help - 4602

	4602	The identifier '%1s' is declared as a macro in '<%2s>'.

Identifiers		REFERENCE - ISO:C90-7.1.2.1 Reserved Identifiers, ISO:C99-7.1.3 Reserved Identifiers

This is a reserved identifier. It is used as the name of a macro defined in the specified library header file.

This is most unwise; if the library header file is ever included in this code, there will certainly be a conflict.

For example:


/*PRQA S 553,2017,2213,3602 ++*/

enum {EOF = -1};                /* Message 4602 - EOF is defined as a macro in <stdio.h> */

MISRA-C:2004 Rules applicable to message 4602:

The names of standard library macros, objects and functions shall not be reused.
