Interesting. We should definitely ask p5p if we shouldn't switch back to 
normal behaviour without the ld2 wrapper, but first I must study history 
on this issue, why we introduced that at all.

Switching to g++ probably has other issues. Most XS modules are pretty 
fine with gcc, but I wouldn't be sure if all of them are C++ safe.
MS cl is probably not that strict as gnu.
Even xsubpp creates lousy c++ code.

For the start having a wrapper should help use in fixing this inside
ld2 or perlld.
We should detect if the intermediate .o was compiled as c++ or plain gcc.
nm -C $obj|grep "operator new(" for example. Is there a better way?
