finding a circular dependency

[Steven Schveighoffer]

I've been trying to get a modified version of std.process to compile (with  
Lars K's changes) for windows, and phobos finally compiled.

So I built a little test program, compiled it, and I get the following  
error message:

object.Exception: circular dependency in module std.stdio.

Great.  How did that happen?  Being that I didn't write std.stdio, only  
modified it slightly (and certainly didn't change any imports), I haven't  
the foggiest where this problem is.  Given that the runtime can prove  
there is a circular dependency, and apparently knows the names of the  
modules, how about showing me the cycle?

:P

I do not look forward to tracking this one down...
