Guys, this is all very well and good if one wants *all* the syscalls
in that package to be accessible with their Unix names, but in the case
of the original poster's question the following might be a lot simpler:

	#+clisp (setf (symbol-function 'getpid)    ; in the using package
		      (symbol-function 'system::program-id))

[I apologize if this isn't the "proper" way to do that, but after a
half-hour of wandering around in the PACKAGE & SYMBOL dictionaries
in the CLHS looking for "RENAMING-IMPORT" or equiv., I gave up and
went with the brute-force approach.]

Or perhaps even:

	#+clisp (defun getpid () (system::program-id))

Since one never needs to call it more than *once* per process,
the overhead of the extra subroutine won't matter.

What am I missing here?
