Compiler Error C2379

formal parameter number has different type when promoted

The type of the specified parameter is not compatible, through default promotions, with the type in a previous declaration. This is an error in ANSI C (/Za) and a warning with Microsoft extensions (/Ze).

The following sample generates C2379:

// C2379.c
// compile with: /Za
void func();
void func(char);   // C2379, char promotes to int
