Most of those undefined references you will be able to fix by switching 
from ascii to wide versions. Like CreateFileA -> CreateFileW, since 
wince is fully unicode (only).

And, the cegcc runtime has a notion of current directory. :)
I'm waiting for you at our mailing list ;)

Thank you too, for making D possible in Windows CE. I will try D when
you have this working ;) I have been reading these newsgroups for ages,
but never really tried D.
