[Greg Hudson via RT]

Visual Studio 2015 build fixes

Define HAVE_VSNPRINTF for VS2015 or newer.  Avoid putting constants
directly after string literals without whitespace, or the VS2015
compiler thinks it's a string suffix.  Prefix the OVERFLOW identifier
in x-deltat.y (along with NUM and LONGNUM for consistency) to avoid a
conflict with math.h.  Regenerate deltat.c.
