    This file contains the declarations of internal compiler helper
    routines. That means you can *NOT* call these directly, as they may
    be changed or even removed at any time. The only reason they are
    included in the interface of the system unit, is so that the
    compiler doesn't need special code to access their parameter
    list information etc.

    Note that due to the "compilerproc" directive, it isn't even possible
    to use these routines in your programs.

    the debugger. The compiler will set the correct size of the array
    internally. It's now set to 0..0 because when compiling with -gt,
    the entire array will be trashed, so it must not be defined larger
    than the minimal size (otherwise we can trash other memory) }
