== Why is this an issue?

If a re-declaration has compatible types but not types which are token-for-token identical, it may not be clear to which declaration that re-declaration refers.


=== Noncompliant code example

[source,cpp]
----
typedef int32_t INT;

INT i;
extern int32_t i; // Noncompliant

extern void f ( INT );
void f ( int32_t ); // Noncompliant
----


=== Compliant solution

[source,cpp]
----
typedef int32_t INT;

INT i;
extern INT i; // Compliant

extern void f ( INT );
void f ( INT ); // Compliant
----

Also, in the message, will it be possible to give a hint about where that previous definition is located? Line # in same file or File name & line #?
