i have some solution for glibc. how to make a patch from it?

Hi. I send this thing to libc-alpha, but they said that they want
patches. So i'd like to make one. How should i do that? Is it enough to
get newest cvs and make patch in unified format or you use some special
switches? how to mark my messege, that it contains a patch?
And this is the message:


I'd like to adress some problem with glibc. In Linux From Scratch
project you have to use some sed substitution during glibc compilation
to change default interpreter of ldd.bash.in (from @BASH@ to /bin/bash).
It's because when configure discovers that only sh is available.
It's simple:
change the line:
BEGIN
if set -o pipefail 2>/dev/null; then
END
to 2 lines:
BEGIN
if set -o | grep pipefail 1> /dev/null 2> /dev/null; then
  set -o pipefail 2> /dev/null
END
Now it'll work with dash too.
Thanks.
