/* Recent MinGW-w64 releases define snprintf and vsnprintf as macros
   that can't be redefined; these are necessary to make our substitutions
   of the trio replacements.  We need the replacements because msvcrt.dll
   doesn't support hex formatting of floating point numbers, and all (?)
   versions of the MS run-time use three digits in floating point
   E formats, e.g. 1.E000. The replacements also allow printing long long
   integers via %lld which the MS run-time does not (and "%I64d" is not
   C99). */
