This is a wrong D2 program:

int x = 1;
int x = 1;
void main() {}


dmd 2.048 prints a good enough error message:
test.d(2): Error: variable test.x conflicts with variable test.x at test.d(1)


This is another wrong D2 program:


void foo() {}
void foo() {}
void main() {}


But here dmd 2.048 on Windows shows a link error:

OPTLINK (R) for Win32  Release 8.00.2
Copyright (C) Digital Mars 1989-2009  All rights reserved.
http://www.digitalmars.com/ctg/optlink.html
test.obj(test)  Offset 00151H Record Type 00C3
 Error 1: Previous Definition Different : _D4test3fooFZv


In my opinion here it's better for dmd to spot the function foo() duplication and give a cleaner error message, something like:

test.d(2): Error: function test.foo() has the same signature as the function
test.foo() at test.d(1)

This bug may happen if a function is duplicated, or if the overloading is done in a wrong way.

This shows a related problem:

> And a note: had forgotten to add an empty main(), just for compiling: the linker produced a rather big amount of error text without any hint to the actual issue. Maybe dmd could cope with that before calling gcc?

I agree, it's better if DMD gives a nice and clean error message when the
main() is missing.
