Hi,
with DMD v0.125 on Widows XP:

import std.stdio;
 
void print(bool b)
{
  writefln("#B: ", b);
}
 
void print(bit b)
{
  writefln("#T: ", b);
}
 
int main()
{
  print(true);
  print(false);
}

testBool.d(15): function testBool.print called with argument types:
(bit)
matches both:
testBool.print(bit)
and:
testBool.print(bit)
testBool.d(16): function testBool.print called with argument types:
(bit)
matches both:
testBool.print(bit)
and:
testBool.print(bit)

If 'bool' is an alias then the error should be the duplicate definition of the
function.
If 'bool' is a typedef then the program should compile.

This reminds me a question: why is 'bool' an alias and not a typedef?

Ciao

Known DMD bug:
http://dstress.kuehne.cn/nocompile/alias_05.d

Use GDC to detect this kind of problems properly.
