Even with Studio, there are now at least 7 different binary incompatible
options for building C++ code:

  -compat=4 - pre-C++98 SunPro 4.x compiler ABI (only in Studio 12.2 & older)
  -compat=5 (aka -std=sun03) - C++03 Sun compiler ABI
  -compat=g (aka -std=c++03) - C++03 with g++ extensions/ABI
  -std=c++11 - C++11 features & g++ library/ABI (only in Studio 12.4 & later)
  -library=Cstd - C++03 with Studio libCstd library
  -library=stdcxx4 - C++03 with Apache stdcxx library
  -library=stlport4 - C++03 with STLport library

As you'll see in the CC man page, all C++ code in a program must use the
same -compat, -std, & -library flags - you can't use a library built with
different ones than the program itself uses.
