A simple testcase:
 #include <tr1/regex>
 int main() {std::tr1::regex r("^$"); }
--- CUT ---
Does not link.  It did with 4.3 though. 
/tmp/ccyEcV0U.o: In function `std::tr1::basic_regex<char,
std::tr1::regex_traits<char> >::basic_regex(char const*, unsigned int)':
t.cc:(.text._ZNSt3tr111basic_regexIcNS_12regex_traitsIcEEEC2EPKcj[_ZNSt3tr111basic_regexIcNS_12regex_traitsIcEEEC5EPKcj]+0x73):
undefined reference to `std::tr1::basic_regex<char,
std::tr1::regex_traits<char> >::_M_compile()'


-- CUT ---
I noticed that std::tr1::basic_regex::_M_compile in 4.3 was just an empty
function in 4.3 but an external function in 4.4 and above.
