[tahoe-dev] Errors building on Windows 7 64-bit

[Kyle Markley]

I've recently been creating a heterogeneous tahoe grid on several
different operating systems -- OpenBSD 64-bit, Windows XP 32-bit, Windows
Vista 32-bit, and Windows 7 64-bit.  The first three went relatively
smoothly, although I've had to use the MinGW tips from the
http://tahoe-lafs.org/trac/tahoe-lafs/wiki/AdvancedInstall page.

I'm not so lucky on Windows 7 64-bit.  There I'm getting the following
error output (sorry about any ugly line-breaking):

I can't find any trace of this temporary directory it appears to have been
trying to build twisted in.  I really wish that when dependencies fail to
build, we would leave the build area alone, as it may contain things
useful
for debugging!

Does anyone know what's going on here?  When I googled for one of the
failed references, I found some web pages encouraging people to use mingw,
but I'm already doing that.  (gcc --version says it's version "3.4.5
(mingw-vista special r3)".)  The missing header files look like
significant
problems too, but I don't have enough context to know what they're about.

I know there's a Win7-64 buildbot, so this should be working - somehow. 
:)

My attempt to build was on a virgin Win7 machine that didn't even have
python
installed before I got started, so all the dependencies would definitely
get
built from scratch.  I was using the regular .zip file, not the -SUMO one.
