Ok, it was just an offer since working on TSVN myself would cost me alot
more time (which _is_ money), but as you wish :)

Stefan Fuhrmann:

As far as I know VC8 is going to be released on 7th November 2005. I
already tried VC8 Beta2, too, but the compiler seems to alot lag
features and so does the IDE. I did a 64bit port myself with gcc4 and
linux several months ago, to tell a short story:
We did use VC71 back then and some freakin Makefiles for unix. It became
unmanageable someday, so we switched to SCons (http://www.scons.org) for
building. SCons is able to procude VC71 Project-files. Tody switching
compiler or architecture is quite easy: "scons CC=icl BUILD_ARCH=amd64".
SCons is quite powerful and easy to maintain. We were quite lucky when
it comes to external libraries: stl, zlib and devil were already ported.
The trickiest part was our exceptionsystem and some non C99 code. So I
can't tell you mutch about porting external libraries, but I can tell
you, that VC71 is close to the standard but not close enough *smile*.

I think the last option would be the best for now, since porting
everything might be alot of work. If you take a look at other projects:
they keep all utilies 32bit and provide their users only with a 64bit
driver/explorer-extension. The argumentation they follow is: they will
need to have 32bit support for the next 2-3 years until the majority has
64bit hardware; well sometimes its hard to follow that argumentation.

Well, for me it does not work. I use WindowsXP 64bit multi-lingual
edition with the MUI package for german. I think it looks like as if I
got no chance but looking into it myself ;)
