** ELF32 structures

** V0.1  (15.11.1998) phx
**       First partially working ppc.library emulation. Synchronous PPC
**       tasks, started by runelf, which only use the basic PowerUp kernel
**       functions for I/O, memory and context-switch seem to work fine.
** V0.0  (04.11.1998) phx
**       created
