// Unless documented elsewhere these configuration macros should be considered
// an implementation detail, I'll try not to break them, but you never know.

// Use Sun C++ workarounds
// I'm not sure which versions of the compiler require these workarounds, so
// I'm just using them of everything older than the current test compilers
// (as of May 2017).
