You can configure the standard C++ library in two ways to reduce the code size
and dependencies on external libraries:

1. --enable-cxx-flags=-fno-exceptions

This does currently not work, due to an error in guard.cc which defines
recursive_init_error::~recursive_init_error() and this results in a dependency
on pure.cc and this one pulls in the IO library.

2. --disable-hosted-libstdcxx

This is also broken currently (try to build it).

Embedded targets may provide a hosted C environment, but in some cases it is
useless to provide output messages.  Also the IO library is quite huge.  Two
files in libstdc++/libsupc++ pull in the IO library: pure.cc and
eh_term_handler.cc (via vterminate.cc).  It would be nice to have a configure
option (like --enable-verbose-cxx) to enable or disable the output generation
in these files.
