$ g++-3.4 --version
g++-3.4 (GCC) 3.4.2 (Debian 3.4.2-3)
$ g++-3.4 -c test.cxx
test.cxx: In constructor `s1::s1()':
test.cxx:16: error: no matching function for call to `s::s()'
test.cxx:9: note: candidates are: s::s(const s&)
The statement "no matching function for call to `s::s()'" is wrong. According to
12.5.5 - 12.5.7 the default constructor s::s() is implicitly-declared and
defined but the definition is ill-formed due to "no matching function for call
to `m::m()'". Cheers!
