be called via the static constructor.  If this is changed to a MACRO, then the
pre-processor will create the int64_t, and you only have to call the one function, the
constructor.  Not the two calls to the LMSK().

IOW, the compiler cannot pre-process even *inline functions* when they are part of a
static constructor.  It can however handle macros.
