C++11: sigset not found

This error only happens to me with Solaris 11 and Oracle Solaris Studio 12.4, and only if I add the -std=c++11 flag.

I'm trying to link two .o files to create an executable.
One of the files uses sigset from <signal.h>.
It works without the -std=c++11 flag.

But when I add it, I get the following error:

Undefined                       first referenced
symbol                             in file
sigset                           whatever.o
ld: fatal: symbol referencing errors

I've tried everything .. adding the flags -lstdc++ -lgcc_s -lCrunG3 -lc didn't help either ..

sigset appers to be defined:

As far as I know, using -std=c++11 will use the g++ ABI. Maybe something's messed up with the installation?
