Problem building Serf on Windows

I am setting up a new Windows build machine. I am building our 1.6.12
release and deps zip. I get a problem when it goes to build Serf.

        
Performing Makefile project actions
context.c
context.c(585) : error C2036: 'void *' : unknown size
context.c(1410) : warning C4090: '=' : different 'const' qualifiers
NMAKE : fatal error U1077: '"c:\Program Files\Microsoft Visual Studio
9.0\VC\bin\cl.exe"' : return code '0x2'
Stop.
Project : error PRJ0019: A tool returned an error code from
"Performing Makefile project actions"

Any ideas? I am using OpenSSL 1.0.0a. That is all I can think of
that is kind of different from what I normally have done. Everything
else, including httpd, has built fine.
