/* Use "static NO_COPY_RO" instead of "static const", if the datastructure
should be R/O, but without the "const" qualifier. Typically this is only
required if the static datastructure is "const" in reality, but the Windows
function is defined with a R/W type as argument. Unfortunately this is
often the case. However, make sure to try "const" first, and use
"NO_COPY_RO" as seldom as possible. */
