even if it doesn't have "gzgets()", so one might think we could use it by using our own replacement for "gzgets()". One would be wrong to think so, however, as the "gzseek()" it has doesn't actually work when reading uncompressed files. zlib 1.0.9 has "gzgets()", and fixes that bug, so we rever to checking for "gzgets()" rather than "gzseek()", so that we don't accept pre-1.0.9 versions of zlib, and we get rid of our "gzgets()" replacement. svn path=/trunk/; revision=4702
