[matplotlib-devel] build error in ttutil.cpp on win32

It's been a few months since I've updated and compiled from svn. I got
this error today from rev 3926 (in winxp using msvc71):

>python setup.py build_ext --inplace --force

The latest change for ttutil.cpp was:

Revision: 3696
Author: cmoad
Date: 5:53:21 AM, Friday, August 10, 2007
Message:
added win32 checks for vsnprintf which is _vsnprintf on windows
----
Modified : /trunk/matplotlib/ttconv/ttutil.cpp

So it looks like both the lines that check #ifdef WIN32 are evaluating
as false, even though I'm in win32. I don't know much about C++. As a
hack, replacing vsnprintf with _vsnprintf in the else clauses gives me a
successful build.

Also, perhaps the pre-built freetype and libpng static libraries should
be updated in http://matplotlib.sourceforge.net/win32_static_vs.tar.gz
to get rid of the "found, but unknown version (no pkg-config)" warnings?

Cheers,

Martin
