Wow, I have no idea what that code is doing noodling around in Ds 
internals, but if it works I will be a very happy man. Unfortunately, my 
project fails to compile after adding this code:

F:\Programming\Current\Destroyed>bud main -cleanup -debug -g 
-I.\..\;D:\D\dmd\src\ext -of.\bin\Destroyed.exe -w
D:\D\dmd\src\phobos\internal\gc\gcx.d(42): module win32 cannot read file 
'win32.d'

Although it seems that win32.d lives in the same directory as gcx.d... 
can someone point out what newbie mistake am I making? :-)

Thanks a lot for your help Bill!
