Hi,

Given the following example:

(asdf:oos 'asdf:load-op :cffi)
(cffi:defcfun "srandom" :void (seed :unsigned-int))
(srandom #x80000000)

with Clozure Common Lisp Version 1.3-r11936  (LinuxPPC32) I receive
the following error:

> Error: value 2147483648 is not of the expected type (SIGNED-BYTE 32).
> While executing: %FF-CALL, in process listener(1).

The attached patch (to level-0/PPC/ppc-def.lisp) appears to correct this issue.

Cheers,
