Fix build failure on Visual Studio.

Unlike clang, VS didn't like me using the value of one 'static const'
integer variable to compute the value of another, and complained
'initializer is not a constant'. Replaced all those variables with an
enum, which should also more reliably ensure that even an
unsophisticated compiler doesn't actually reserve data-section space
for them.
