No, these functions where there only temporary. The RTL functionality 
for semaphores was only ever implemented for *nix systems, but not for 
Windows and was only used internally in the System unit, but even that 
changed some years ago, thus it was decided to remove it.

The way to go with semaphores would be to implement the Delphi 
compatible TSemaphore in the unit SyncObjs.
