Maybe this helps. Using ./configure --without-gcc .... in Python 2.5.1 on Solaris 10 gives a different message. That message indicates that C++ compiler 'c++' will be used but the Studio C++ compiler on Solaris is 'CC'.
Using ./configure --without-gcc --with-cxx-main=CC .... made that message go away. Python did build after that and the tests are running. But it is a 32-bit binary, not 64-bit. Another ./configure option will be needed to build that. /Jean Brouwers -- http://mail.python.org/mailman/listinfo/python-list
