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.

------- Comment #2 from redi at gcc dot gnu dot org  2010-04-22 14:51 -------
So this should be three bugs, one for each of the build problems and one
enhancement request for a semi-hosted environment.  I don't think "verbose" is
a good name for the default case, I would prefer something like "quiet" for
your suggested new mode

------- Comment #3 from paolo dot carlini at oracle dot com  2010-04-22 17:02 -------
Good point about splitting to two or three bugs, because the build issues can
probably be fixed in the 4_5-branch too.

Lets call it quiet.

Configure option may be --enable-quiet-cxx.

Yes, however as you don't have a copyright assignment in place, submitting
these patches might actually make it *harder* for us, as we can't use your work
if it's anything substantial.

I'll get this and Bug 44647 done for 4.6.0
