Peter Wemm 0143afc23b - overhaul for unlimited file descriptors
- prototypes now in include files

Obtained from: a diff of FreeBSD vs. OpenBSD/NetBSD rpc code.

Note: potential bug here, It looks like there could be a null pointer
dereference depending on what has already been called to initialise some
shared data.
