 {{{__STDC_LIMIT_MACROS}}} is defined or not, so rather like assert.h with
 {{{NDEBUG}}} it should really "correct itself" each time it's included
 depending upon the value of the macro.  Thankfully C++11 does the sane
 thing and just requires that the limit macros are always defined.

 Thanks for the explanation, I didn't know about this requirement.

 > Either way, we should really try to get the system defined limits macros
 if we can, just because we can't be certain of getting them every time,
 isn't a reason not to try.

 Agreed.
