Thanks for the bug report. I think you have an old-fashioned shell
that doesn't understand "(" in the front of shell case labels. To
work around the problem, you can set the SHELL environment variable to
the fully-qualified name of a modern (i.e., POSIX-conforming) shell
before running 'configure'. This should cause zgrep to use a better
shell and avoid the bug.
I have installed the following patch to gzip, so that its build
procedure detects the problem in future gzip versions.

* m4/shell.m4 (AC_PROG_SHELL): Check for old-fashioned shells that
don't allow "(" in front of case labels. Problem reported by midair
in <http://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00004.html>.
Also, check for buggy shells that require ";;" before "esac".
