// Defines all the patchable constants in fbscli.dll.
sl@0
    15
// The definition of the constants must not be in the same file as the usage,
sl@0
    16
// or the compiler will optimise them out, so put them all in here.
sl@0
    17
// Note that existing patchable constants are declared as global,
sl@0
    18
// i.e. not in a namespace, so I have continued the trend.
