Yes. > If there is some library with such objects that happens to get > wrapped and dynamically linked into a Python interpreter Whoa there. How would that ever happen under ordinary circumstances?

Right, and linking would fail, IIRC. It seems to me that if someone decides to build a wacky Python executable that links in C++ code directly, they can afford to use a configure option. There's no need to punish all the other writers of C++ extension modules out there by tying the default build of Python to a particular version of libstdc++. > Dave> Boost.Python is a library written in C++ and I've never had > Dave> trouble using it with a Python executable... until I ran into a > Dave> Python that was linked with libstdc++! > > Sorry, I can't help.

If there's someone around here who is responsible for this change and knows its real rationale, can (s)he please tell me what it is? If not, can we please change things back so Python doesn't get linked to the C++ runtime by default?
