In general it is a Really Bad Idea™ to link object files created with
different ABI standards (including C++ standard, but there are also
other settings that affect this), or that use a different libc/STL.

Sometimes you can get away with linking files created by different
compilers (in particular I think GCC and Clang are designed to be
interoperable, provided you're using the same C++ ABI and libc
settings), but in general you should try to avoid that too.

If you're using DLLs/SOs and the API is designed *really* carefully,
then you may at times be able to interoperate with different
compilers/libc, but this is quite tricky unless you stick with a pure C
API (since the C ABI is simpler and more stable).
