Including the C++ compiler?

This error means that "g++" failed to successfully compile a C++
program consisting of:

int main() {}

So either g++ isn't installed, or it's not working well at all!  You can
look at config.log to see what happened in detail.

With Xapian 1.0.x you may need to explicitly specify to link with -lm for
the Sun compilers:

./configure CXX=/opt/SUNWspro/bin/CC LIBS=-lm

(I've had a report that this was needed, but I believe James has managed
to build with Sun compilers on Solaris without doing this, so maybe it
depends on the version of the compiler or something...)
