> If we add preproc directives:
> 
> struct A
> {
> #if A
>   int a;
> #else  
>   int b;
> }
> #endif
> 
> Now the parser will parse the "struct A {“ individually; parse “int a;” individually; and parse “int b; }” individually.
> 
> So in general, if a preproc directives butchers some construct, the first part is usually fine (eg, the “struct A {“ part), but the rest often have problems. Like a dangling “else if {}” in if-else-if, or a dangling “xxx }” in a function definition, or maybe a “default: xxx }” in a switch-case.

Thanks.
