Oh yes!  Under Windows MSVC and under gcc, we have a zero-tolerance policy
for compiler warning messages.  It's appalling to see all these warnings
coming by from other platforms.  We don't want to see any warnings precisely
so that seeing one is always a red flag; paying attention to warnings is the
cheapest line of defense against accidental reliance on non-portable
assumptions.
