How to build EPICS3.13.1 for PPC?

[shen guobao <shengb@ssrc.ac.cn>]

Hello,
I use EPICS3.13.1, vxWorks5.3.1(PPC2303). My host is Sun/Solaris2.7,
target is MV2302 board(PPC603).
Now I want to build base for PPC, I have modified some files.
In CONFIG_SITE_ENV:
I set 'CROSS_COMPILER_TARGET_ARCHS=mv2303'
And I create the CONFIG.Vx.mv2303:
'
# $Id: CONFIG.Vx.mv2303,v 1.1 1998/06/04 19:15:13 wlupton Exp $
#
# This file is maintained by the EPICS community.
# Vx GNU cross compiler suffix
CMPLR_SUFFIX = ppc
 
# For Vx directories of form:
#   $(VX_DIR)/$(HOST_ARCH).$(ARCH_CLASS)/bin
ARCH_CLASS = ppc

# Architecture specific build flags (TRUE=1 via LBL; needed in
camessage.c)
ARCH_DEP_CFLAGS = -fno-for-scope -DCPU_FAMILY=PPC -DCPU=PPC603
-D_GNU_TOOL -DTRUE=1
'
But when I use gnumake in the epics/base/ , it gives the following
errors:
"

How can I do?
