[previous] 0801 [next] [C] The '##' operator may not be the first token in a macro replacement list.
Constraint violations REFERENCE - ISO:C90-6.8.3.3 The ## Operator - Constraints

This is a constraint error

The glue operator, '##', has appeared as the first token in the replacement list of a macro. This makes no sense because the function of ## is to join the tokens on either side of it when the macro is expanded.

For example: 


/*PRQA S 553,2017,3429 ++*/

#define GLUE(b) ## b           /* Message 0801 */
