You have already been told how to reduce the program size (-N).
I grabbed the SLS sed a couple of weeks ago and found problems
with it. It is (was) version 1.09, and the problems turned out to be
in libc.so.4.2. If you look in <regex.h> you will see a flag called
RE_NO_BK_PARENS, and it appears the state of this flag has been toggled
between 4.1 and 4.2. This causes sed to fail, as a `group' is now
defined by (...) rather than \(...\).
H.J.Lu appears to indicate this is a change in the original library, not
just the Linux version. Somewhat stupid, that. Now you have to compile
sed (and I presume other programs too) with their included regex code.
So what are libraries for, anyway ?
