Hi John,

 nm /path/to/libstdc++.a | c++filt | grep compare

shows the following:

[jjw at oktoberfest| lib]$ nm libstdc++ dot a | c++filt  lib]$ nm libstdc++.a | c++filt | grep compare
00001fb8 T basic_string<char, string_char_traits<char> >::compare(char
const *,
unsigned int) const
000011bc T basic_string<char, string_char_traits<char> >::compare(char
const *,
unsigned int, unsigned int) const
000010bc T basic_string<char, string_char_traits<char>
>::compare(basic_string<c
har, string_char_traits<char> > const &, unsigned int, unsigned int) const
000000c0 T string_char_traits<char>::compare(char const *, char const *,
unsigne

0000021c T __fast_compare(char const *, char const *)

0000002c T type_info::__rtti_compare(type_info const &) const


I haven't had time to look at the SPARC20 problems yet, but I'll report
back soon:)


Take care.
