Actually the compiler does not always have a choice to warn about a ambiguity.
Example
int f( sal_Int16 n);
and code like
sal_Int8 n1 = 3;
f( n1 )
Here f( n1 ) will call f( sal_Int16 n) from global namespace.
If we now have a header file A.hxx like
namespace A
{
int f( sal_Int8 n)
}
and somehow, maybe just implicitly not even done in our code, the file A.hxx
gets included along with a
using namespace A;
somewhere else then
f( n1 )
will no longer implictly conver the sal_Int8 to sal_Int16 and then call the
original function as before, because now A::f will have an exactly matching
parameter and thus now A::f gets called and likely even without the compiler
giving any notice about it at all...
