I don't observe any problem with gzip 1.3.8.  Do you?  Here's
how I tried to reproduce it:

  wget ftp://alpha.gnu.org/gnu/gzip/gzip-1.3.8.tar.gz
  zgrep -a . gzip-1.3.8.tar.gz | less

I observed no problem with "Broken pipe" errors.

This is running on Debian stable x86, built with GCC 4.1.1.

I did manage to reproduce the problem by ignoring SIGPIPE in the
parent process before invoking zgrep.  But that's the calling
process's screwup, not zgrep's.  (And I got the same problem with
plain grep, so zgrep is compatible.  :-)
