Enabling Checks for this warning class are disabled by default, and require the unnormalized C ASTs for the project. To enable them, add the following WARNING_FILTER rule and RETAIN_UNNORMALIZED_C_AST specification to the project configuration file. 
RETAIN_UNNORMALIZED_C_AST = Yes
WARNING_FILTER += allow class="Macro Defined in Function Body"
Note that retaining the unnormalized ASTs will increase the disk space used to store the project representation, and may make the analysis take longer.

Example 

void lang_preproc_definfn(char *inchar){
/* 'Macro Defined in Function Body' warning issued on following line */  
#define CLEAR(x) q->x = 0 
}
