The examples only work with GCC 4.9.4 because the abi_tag doesn't have any
effect before GCC 5, but it's still a regression because of the effect on
std::string variables, which are now tagged.

Without the header:
cat > a.cpp <
thread_local std::string gFeelingLucky;
EOF
cat > main.cpp <
extern thread_local std::string gFeelingLucky;
int main() {
return gFeelingLucky.length();
}
EOF

No, using header guards makes no difference.
