Ok, maybe we can get this fixed, somehow. :-)

I installed GDC from cygwin's setup tool. If I run,

```
$ gdc -v
Using built-in specs.
COLLECT_GCC=gdc

```

you can see that it's install, but when I try to compile this 
very basic HelloWorld.d program,

```
$ cat HelloWorld.d
import std.stdio;
void main()
{
   writeln("Hello world");
}
```

I get these error:

```
$ gdc HelloWorld.d
d21: error: cannot find source code for runtime library file 
'object.d'
d21: note: dmd might not be correctly installed. Run 'dmd -man' 
for installation instructions.
d21: note: config file: not found
```

What do I need to do to get gdc to run in cygwin?

Is there a list of instructions on how to get this to work in any 
place?

It should be simple by copying certain files to the cygwin file 
structure. Thanks.
