 Good point. :-) But let me change the PR into a feature and
 documentation  request:
 
 a) http://gcc.gnu.org/install/configure.html does not mention
    --enable-__cxa-atexit at all. I found it only when I ran
    `gcc/configure --help'. I guess you need to supply this option if
    you want to use the compiler option -fuse-cxa-atexit?
    Or does it make -fuse-cxa-atexit the default?
 
 b) configure should complain if --enable-__cxa-atexit was passed but
    is not supported rather than produce linker errors at the end of
    the build process.
 
 Nevertheless, thanks for the clarification!
 
 Regards
 
 Christoph
