RULE-8-13: Consider possible macro false positives

[lcartey]

Affected rules

• RULE-8-13

Description

Should we flag variables generated from macro expansions as missing const?

Some considerations:

• Should we flag the macro itself, as that's where const would need to be added?
• If so, should we only flag if the variable could be const in all instantiations of the macro?

Example

#define FOO int x = 0;

..
int f() {
  FOO; // NON_COMPLIANT?
  return x;
}
