GTK compile error: ../gdk-pixbuf/gdk-pixbuf-enum-types.h:19:9: error: macro names must be identifiers

["Kristin Branson" <kristinbranson gmail com>]

I am trying to compile GTK, and have encountered an error I can't figure out. Here is the tail of what make spits out:

Here is the configure command:
./configure --prefix=$HOME/vision/local --exec-prefix=$HOME/vision/local --without-libjasper

Because most of the required packages were installed locally, here are the updates I've made to various environment variables:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/users/branson/vision/local/lib:/home/users/branson/vision/local/lib64
export PATH=/home/users/branson/vision/local/bin/:$PATH
export CC=$HOME/vision/local/bin/gcc
export CPP=$HOME/vision/local/bin/cpp
export CXX=$HOME/vision/local/bin/g++
export LDFLAGS="-L$HOME/vision/local/lib -L$HOME/vision/local/lib64
export CPPFLAGS=-I$HOME/vision/local/include
export PKG_CONFIG=$HOME/vision/local/bin/pkg-config

The machine has a 64-bit, 8-core Intel CPU, and is running Linux CentOS release 4.7.

Any suggestions would be much appreciated!

Thanks,
Kristin
