@Stable libpru will compile.
@Head libpru will generate following errors:

The mission is just to make it compile.
I have verified the binary (libpru + pructl) can load and execute a program on a PRU on AM3358 (BBBlack/PB).
I did not perform an analysis of the code for each errors but made reasonable decisions from the small context.
