Can't build lib due to exception model?

[Jerry Quinn]

Some more info on the problem I'm having ...

During configure I'm getting:

checking for exception model to use... configure: error: unable to detect exception model
make: *** [configure-target-libstdc++-v3] Error 1


It seems to be similar to the problem I had recently where the wrong compiler
is used during configuration.  At the end of config.log where the configure
fails, I have the following:

configure:2741: checking for exception model to use
configure:2767: c++ -c -S -O2 -g -O2 conftest.C 1>&5

On my machine, c++ is 2.95.4.  Also, confdefs.h contains:

#define PACKAGE "libstdc++"
#define VERSION "2.95.4"

I don't know how my build dir is getting messed up like this.
