compiling with GCC 6.3.1, ERANGE’ was not declared in this scope

When I try to compile with GCC 6.3.1, I get;

$ make
cc  -c HarmonyHubControl.cpp csocket.cpp -lstdc++ 
HarmonyHubControl.cpp: In function ‘int swapAuthorizationToken(csocket*, std::__cxx11::string&)’:

FWIW, with compat-gcc-34-c++ it does build.

$ CC=/usr/bin/gcc34 make
/usr/bin/gcc34  -c HarmonyHubControl.cpp csocket.cpp -lstdc++ 
gcc34: -lstdc++: linker input file unused because linking not done
/usr/bin/gcc34  HarmonyHubControl.o csocket.o -o HarmonyHubControl -lstdc++

I get an executable even though the linker input file was not used.

list_devices and list_commands work seemingly fine, list_activities only shows
