Comment (by lcarreon@…):

 FYI, I tried implementing the code change mentioned above. It is now
 complaining about

 "./boost/thread/pthread/once_atomic.hpp", line 168: Error: Overloading
 ambiguity between "boost::detail::invoke<void, void(*)(rlimit*),
 rlimit*>(void(*)(rlimit*)&, rlimit*)" and "boost::detail::invoke<void,
 void(*)(rlimit*), rlimit*&>(void(*)(rlimit*)&, rlimit*&)".

 Looking at the line being complained above, I realized it is in the part
 of the code where there is no support for variadic templates and rvalue
 references. IMO, this is incorrect
 because according to the Solaris Studio 12.4 documentation, it does
 support these two C++11
 features in C++11 mode. Only thread related features are missing. I'm
 not sure if there is a way to distinguish if the compiler is in C++11 mode
 or not.

 Taking the above into consideration, I undid your changes described above
 and changed the
 boost/config/compiler/sunpro_cc.hpp file instead to move
 to affect Solaris Studio 12.3 and below only. This new change has
 eliminated all the
 boost::call_once related errors but it did generate signal 11 errors in
 various libraries
 as mentioned in a comment in the compiler configuration file. It also
 generated template argument errors in Boost.Log and Boost.Variant (1 line
