As the RTL can be switched to "don't use those functions", as I've 
described, the impact should be low.

Note: You do that switch in your main program as well as the 
variable/constant is available in the implementation section of the 
system unit (maybe you need to enable "writable typed constants"). Then 
a stub would be sufficient.
