Yes, but I used a pixman from the git repository instead of the 0.9.6 
release. I got that by typing this:

git clone git://anongit.freedesktop.org/git/pixman

That bug is unfortunately still in the version I got from git. The 
problem is that the macro ends with a ';', but both uses of the macro 
also append a ';', resulting in two successive ';' which throw MSVC off. 
Just remove the ';' after both uses of YV12_SETUP and it works (see 
attached diff).

Maybe someone on this list can commit that to the pixman git repository.

The pixman from git comes with a "Makefile.win32" that does not use 
either pixman-mmx.c or config.h. The resulting file pixman-1.lib is 
still sufficient to build cairo 1.5.2.

However, I didn't find a MSVC makefile in the cairo 1.5.2 distribution, 
so for me building 1.5.2 with MSVC required more manual labor. Also, the 
resulting dll worked fine for screen output, but crashed very frequently 
when using pdf output (in code that works fine with 1.4.10). I haven't 
yet found the time to investigate that further.

You decide whether your needs justify the effort to build 1.5.2. If you 
do it, and have an appropriate test case, please let me know how pdf 
output works for you.

Best regards,
