That should work fine.  I'm not familiar at all with internix, but it
appears to have a buggy header or something.  From what I understand,
internix is a posix layer for windows.  Have you tried compiling under
cygwin?  If you grab the latest CVS sources, they should work fine with
cygwin, and will probably work better with windows in general than LLVM

Again, I'm sorry that I don't know more about this and why <cstring>
apparently doesn't have strdup, it seems really odd.  If <cstring> doesn't
work, you could try <string.h> explicitly, but it would be much better to
use cygwin if you can.
