Hi, I've been having the following kind of problem ever since the new
binutils were introduced:

--CLIP--
all ===> gnu/usr.bin/binutils/ar
cc -O  -Werror  -I/usr/src/gnu/usr.bin/binutils/ar

*** Error code 1

Stop.
--UNCLIP--

I run NetBSD/i386 and the above was output of 'make build'

Any help, corrections, RTFM suggestions etc. welcome.

Thanks,
