PPC should not use -fno-builtin (was Re: 2.3.47 imac build?)

Well, no... unsigned long is 32 bits wide when compiling for 32-bit
machines, 64 bits wide when compiling for 64-bit machines.

Anyway, I have caved in and put the following ugliness in
asm-ppc/posix-types.h:

#include <linux/config.h>	/* for CONFIG_PPC64 */

[snip]

/* Grrr... gcc thinks size_t is unsigned int, so we either
   have to have this nonsense or use -fno-builtin. - paulus */
#ifdef CONFIG_PPC64
typedef unsigned long	__kernel_size_t;
typedef long		__kernel_ssize_t;
#else
typedef unsigned int	__kernel_size_t;
typedef int		__kernel_ssize_t;
#endif /* CONFIG_PPC64 */

My linuxcare.com.au::linux-pmac-devel rsync tree is now up to 2.3.48, BTW.
