With --enable-build-with-cxx I see

In file included from ada/b_gnatb.c:252:
ada/b_gnatb.c:5: error: previous declaration of 'void exit(int)' with 'C++' linkage
/usr/include/stdlib.h:543: error: conflicts with new declaration with 'C' linkage
/usr/include/stdlib.h:543: error: declaration of 'void exit(int) throw ()' throws different exceptions
ada/b_gnatb.c:5: error: from previous declaration 'void exit(int)'
Comment 1 Laurent GUERBY 2010-06-06 12:35:04 UTC 
The Ada language build issues were all adressed by my patch on june 2009 here:

http://gcc.gnu.org/ml/gcc/2009-06/msg00635.html

The patch for your problem is the gcc/ada/gcc-interface/Makefile.in change to use -A instead of -C for gnatbind.

As I said in the last message of the discussion there are a few choice to make to do the switch to be able to use C++ and an Ada maintainer needs to step in now.

All other languages work fine with C++ now.

The -C mode for gnatbind is to be deprecated so we'll need to make the switch in any cases.  Let's wait for Arno's take on this.

Still fails the same way.
