The only other alternative would be to add the RTL initialization code 
to each exported function. I don't consider this a viable alternative.

Note: Dynamic packages won't have this problem, because:
- for packages linked at compile time the initialization is run as part 
of the program initialization AFTER the OS has initialized the library 
(which doesn't do much in case of a package)
- for packages loaded at runtime it's done as part of the LoadPackage call
That's however only possible, because dynamic packages are very 
different from simple libraries (and stuffed with compiler magic).
