Wow, that's old.  I recall fixing that bug some time ago in the GNU 
sources.  I can't reproduce the problem on the oldest Solaris box I have 
easy access to:

$ echo foo >a
$ echo foo >b
$ echo bar >c
$ gzgrep foo *
a:foo
b:foo
$ gzgrep -h foo *
foo
foo
$ uname -srvmpi
SunOS 5.10 Generic_147440-19 sun4u sparc SUNW,Sun-Fire-280R
$ gzgrep --version | sed 1q
gzgrep (gzip) 1.5

My guess is that you need to bring your Solaris machine up-to-date, by 
installing the usual patches from Oracle.  Probably should be doing that 
anyway, as unpatched machines can be dangerous.

Hello Paul,
    The solaris box is running fully patched 11.1.
The bug is present in Linux zgrep as well.  I can confirm that its present in
RedHat/CentOS 6.2, and ubuntu precice1 which is just a few months old.

    It looks like the version you tested is 1.5.  When was it released and where
can I get it?  Thanks.

That's, odd, because on the Solaris 11.1 box I have access to, gzgrep is 
version 1.5:

$ uname -srvmpi
SunOS 5.11 11.1 i86pc i386 i86pc
$ gzgrep --version | head -1
gzgrep (gzip) 1.5

Perhaps there's some patch set your sysadmins are not installing?

I'm not surprised: those releases were originally made in 2012, and 
predate gzip 1.5.  They probably don't think this bug worth fixing.

I wouldn't install gzip 1.5 (released June 2012); like gzip 1.4, it has 
known security holes (which I hope Solaris has patched).  I'd install 
gzip 1.6 (released June 2013).  Please see:

Thanks for your reply Paul.
I'm no longer involved in the maintenance of the Solaris host on which I tested,
but this is what I see...
09:17:37 rml <at> ieng9:rml:1> uname -a
SunOS ieng9.ucsd.edu 5.11 11.1 sun4v sparc sun4v Solaris
09:17:44 rml <at> ieng9:rml:2> ls -l /usr/bin/gzgrep
-r-xr-xr-x 1 root bin 6010 Apr 15  2013 /usr/bin/gzgrep
09:18:01 rml <at> ieng9:rml:3> /usr/bin/gzgrep --version
gzgrep (gzip) 1.4

Checking an unsupported (so not updated since release of 11.1) VM...
9:29:44 rml <at> sol11-1:rml:3> uname -a
SunOS sol11-1 5.11 11.1 i86pc i386 i86pc Solaris
09:29:51 rml <at> sol11-1:rml:4> /usr/bin/gzgrep --version
gzgrep (gzip) 1.4

I'll bring this to the attention of the group maintaining the OS in question.
Thanks for your work supporting FOSS.
-Bob
