If you drop RTTI and exception handling, you won't need any runtime
support for C++.
I have been told (but don't know for sure) gcc conforms to this:
http://www.codesourcery.com/cxx-abi/abi-eh.html
after reading this, I realised how practical was the -fno-exceptions
and -fno-rtti compile options... :)
the only problem with disabling exceptions is that you cannot do dynamic
allocation within a constructor [unless you can garantee it will
succeed]. if I'm guessing right, you're developping on a small
embedded system so it shouldn't matter much.
