Atm, nothing - we have SLBs - they can be loaded at runtime. But an app 
has to do it on its own.

A better solution would be a proper unix style dynamic (shared) 
libraries suppoert with ELF binary format, ld and so on. This way we 
would have dynamic libs support for all uinx software out-of-the-box, 
and a simple hello world program compiled with GCC (and MiNTLib if it 
would go dynamic) would be few KB, not half meg :)
