Hi I'm not able to build Gambit with C++ support, having problem with 4.6.7 and 4.6.8.

Building on ubuntu 32bit.

Full log is attached but here are the relevant parts:

gcc 4.7.2

Both configure commands produce same error:

./configure --enable-single-host --enable-cplusplus --enable-c-opt

./configure --enable-single-host --enable-cplusplus
