Re: LSB patch to gcc 3.3 tree

I'm no LSB guy, but I thought it good to mention that the LSB testsuite
would then miss the below symbols (i.e. on 3.3 with the below patch to
export only the mentioned symbols).  I don't know wether this would be
okay for LSB or not:

_ZN10__cxxabiv111__terminateEPFvvE
_ZN10__cxxabiv112__unexpectedEPFvvE
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEE2fdEv 
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEED0Ev 
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEED1Ev 
_ZN9__gnu_cxx13stdio_filebufIcSt11char_traitsIcEED2Ev 
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEE2fdEv 
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEED0Ev 
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEED1Ev 
_ZN9__gnu_cxx13stdio_filebufIwSt11char_traitsIwEED2Ev 
_ZNSt21__ctype_abstract_baseIcED0Ev
_ZNSt21__ctype_abstract_baseIcED1Ev 
_ZNSt21__ctype_abstract_baseIwED0Ev
_ZNSt21__ctype_abstract_baseIwED1Ev

which are demangled this:

__cxxabiv1::__terminate(void (*)())
__cxxabiv1::__unexpected(void (*)())
__gnu_cxx::stdio_filebuf<char, std::char_traits<char> >::fd()
__gnu_cxx::stdio_filebuf<char, std::char_traits<char> >::~stdio_filebuf()
__gnu_cxx::stdio_filebuf<char, std::char_traits<char> >::~stdio_filebuf()
__gnu_cxx::stdio_filebuf<char, std::char_traits<char> >::~stdio_filebuf()
__gnu_cxx::stdio_filebuf<wchar_t, std::char_traits<wchar_t> >::fd()
__gnu_cxx::stdio_filebuf<wchar_t, std::char_traits<wchar_t> >::~stdio_filebuf()
__gnu_cxx::stdio_filebuf<wchar_t, std::char_traits<wchar_t> >::~stdio_filebuf()
__gnu_cxx::stdio_filebuf<wchar_t, std::char_traits<wchar_t> >::~stdio_filebuf()
std::__ctype_abstract_base<char>::~__ctype_abstract_base()
std::__ctype_abstract_base<char>::~__ctype_abstract_base()
std::__ctype_abstract_base<wchar_t>::~__ctype_abstract_base()
std::__ctype_abstract_base<wchar_t>::~__ctype_abstract_base()

So, are stdio_filebuf::fd() and the stdio_filebuf dtors really not usefull 
to export?  What about __terminate and __unexpected?  I guess it's not 
normal code which would call them, but perhaps there would be legitimate 
uses (I really don't know, that's why I ask).


Ciao,
Michael.
