[ECOS] problem when building the arm-elf toolchain (http://sources.redhat.com/ecos/build-toolchain.html).Thanks a lot.

Hi all:

I tried to build the tool chain for arm-elf target (follow the same
instruction in ecos web page 
"Building a toolchain for use with eCos", applied all the patches). ,
I can build GNU binary utilities, Insight 
for arm-elf target without problem, when I came to a make for the gcc
(make -w all install 2>&1 | tee make.out )
I got __memcpy() function not defined problem as shown below(I have
made a search on all the source and couldn't find
__memcpy() definition anywhere):

But I can build it with gcc-3.3, then I can build the ecos library but
when linking with 
ecos user application I got error. 

BTW has anybody use sh ecos-install.tcl recently? I failed to use it
now. (I could use it some
weeks ago, but not now.) Thanks
