It seems you've found a bug.
Recently (~1 month ago), I got a request from one user to change wce_
prefix to something other because MFC on Windows CE include
functions like wce_time.
So, I changed the prefix to wceex_
but it seems I did not updated all places.

>=2 weeks ago, I removed Windows installation + VC++ from my laptop,
so I was not able to build it.

So, thanks for your effort. I'll commit your bug fix soon.

Yes, thanks!

Yes, it's well known warning, but AFAIK it does not cause any problems.
There seems to be a problem with STL stuff on Windows CE, but I'd say
you can safely ignore it for now.

I've not met any problems for last ~3 months.

Sorry, I've never useed emulator for Windows CE development.
It's too far from real environment.
So, I have no idea if it's possible to use STLport on emulator :-(

I suppose you will have to use some preprocessor definitions.

Yes, but I've not compiled DGN driver yet.
