Cross-compiling D for wince

Hi Vincent!

I think I've dealt with this before, but it was like 3 years ago.  I've 
forgotten a lot about it since then.

This might have been a symptom of the configure scripts passing the 
wrong version flags to the compiler.  I think when I first started my 
port, it was not passing in version="Win32" but it needed to.  At least 
making it do that made things way easier.  Look at target-ver-syms.sh in 
the root of the gdc folder (that folder that you copy into your gcc 
source before compiling gdc -- ./gcc/d from the gcc source root).  Diff 
that and maybe phobos/configure and phobos/configure.in against the ones 
that I made (link below).  This may fix your problem, or fix a problem 
you are going to have in the future (unless David/gdc already made some 
changes for arm-wince).

Here's a link to the old work I did before running out of time:
http://post-boredom.net/arm-wince-pe-root/

I think I made that off of v18 of gdc, or something one off from that. 
At any rate, you should be able to diff my files against an old version 
of gdc to see what I did to the config files and phobos source in 
particular.  Heck, maybe you could even get away with diffing it against 
a new version of GDC.

It's also great if you are able to build this from an unmodified cegcc. 
  I remember being unable to do that because cegcc was version 4.1.x of 
gcc, and gdc wouldn't build with that at the time.  If you can do that, 
it will be awesome and eliminate an entire class of changes I had to 
make to gcc at that time in order to make a vanilla gcc compiler compile 
to arm-wince correctly.

Good luck with your cross-compiler!
- Chad
