Whoops, no, not really. Thank you for this hint.
I followed your suggestion to update the 
NetBSD-current-branch via cvs update -A -rnetbsd-1-6 -dP.
But the build process seems to have some difficulties with 
this approach, so I simply have downloaded a clean, new NetBSD 
source tree from
	ftp://ftp.de.NetBSD.org/pub/NetBSD/NetBSD-release-1-6/tar_files/src/
unfortunately the build process now ended with the following error, 
which has occurred during a call of "i386--netbsdelf-gcc". 

------------------------------------------------------------------> SNIP
i386--netbsdelf-gcc: cannot specify -o with -c or -S and multiple
compilations
*** Error code 1

I used this commands:
        cd /usr/src
	./build.sh -m i386 -D /pub/release/i386

Any suggestion would be appreciated.
(Which source tree do you would use for building standard NetBSD 1.6.1
binarys (NOT current)).
