This is with the 1.4.1 NetBSD make?

Looks fine.

Nope. The 1.4.1 version should work.

I saw that. Very strange. It looks like it should be working.

The way these files get built is that the kernel's Makefile includes
libkern's make file with this line:

.include "$S/lib/libkern/Makefile.inc"

This include file adds some rules to the make process, including one which
will fork off a copy of make to actually make the library. That make will
define a variable M, and use it to find the powerpc-specific includes:

ARCHSUBDIR= ${MACHINE_ARCH:C/mipse[bl]/mips/}
M= ${.CURDIR}/arch/${ARCHSUBDIR}

CPPFLAGS=       -I$M ${KERNCPPFLAGS} ${KERNMISCCPPFLAGS}

.if exists ($M/Makefile.inc)
.PATH:  $M
.include "$M/Makefile.inc"
.endif

So sys/lib/kern/arch/powerpc/Makefile.inc isn't getting found.

I don't understand why.

Take care,

Bill
