/* Work around a particularly pernicious and deliberate bug in Visual C++:

* consequences. This compiler bug can be switched off by defining NOMINMAX.
*
* We don't like making choices for the user and defining environmental macros
* of our own accord, but in this case it's the only way to compile without
* incurring a significant risk of bugs--and there doesn't appear to be any
* downside. One wonders why this compiler wart is being maintained at all,
* since the introduction of inline functions back in the 20th century.
