Strange error message with alias

[Roberto Mariottini]

Hi,

===============================
alias int A;

void f(int x)
{
}

void f(A x)
{
}
===============================

Gives the following error message:

===============================
C:\Down\dlang>dmd test.d

===============================

IMHO the compiler should issue an error before the linker complains for 
a duplicated identifier. It is also difficult to find which symbol is 
duplicated.
