Testcase to illustrate C / C++ differences:
typedef struct { } T1;
typedef T1 T2;
void foo (T1 a, T2 b)
{
}
TYPE_MAIN_VARIANT of the type of a is T1 for C++, struct {} for C.
TYPE_MAIN_VARIANT of the type of b is T1 for C++, struct {} for C.
typedef struct X { } T1;
typedef T1 T2;
void foo (T1 a, T2 b)
{
}
TYPE_MAIN_VARIANT of the type of a is struct X {} for C++, struct X {} for C.
TYPE_MAIN_VARIANT of the type of b is struct X {} for C++, struct X {} for C.
