proc_task2proc prototype change

Hello,

Copy/pasting the whole story again, since it was hidden behind an
unrelated issue.

Indeed, rebuilding glibc gives:

hurdexec.c:72:29: error: too few arguments to function ‘__proc_task2proc’

because client RPC stubs are built by glibc that went unnoticed.

Do RPC-knowledgeable people know a way to have this change happen in the
server only?  Perhaps just using a typedef which will not be the
same in the server and the client?
