If CXXFLAGS, is this a potentially surprising departure from
previous configure behavior?
Perhaps. I don't see how we could reasonably make any other choice,though.
Agreed. Just wondering if there might be potential documentation impact,

This new build behavior broke former plugins built with gcc. Indeed,
all cc1 function symbols are now mangled and thus with the current
trunk, plugins should also look for mangled symbols (and so built
with g++).
What's the new GCC policy

However, since we currently permit plugins to call anything in gcc, I
think the answer is going to have to be that plugins which do that
should be compiled with C++.
Ok, i'll move to C++ then, until a dedicated C plugin API comes out.

This is not the global constructor/destructor issue with names
generated by collect2. But ELF or SVR4 is able to provide a unique
name without resorting to random numbers.
Not clear if the name needs be unique at all if you have the right features,
