Consider the following two modules: 1. test.d:
module test;
import lib.a;
void main() {
foo();
}
2. lib/a.d:
module lib.a;
extern(C) void foo() {}
When compiled separately (dmd -c lib/a.d; dmd test.d a.o), the
function in 'a.o' is mangled as 'foo', but the reference in
'test.o' is mangled as '_D3lib1a3fooFZv', which leads to a link
error. I would expect both of them to be either plain C mangling,
or fully qualified D (better). What is the reason for current
behavior?
