Of the "zlib" functions we use that aren't in all versions of "zlib",
"gzgets()" is the one most recently added; it was added in 1.0.9.
Check for it, rather than for a list of functions, when checking for
"zlib" support - if you check for N functions, and they're all there,
you get N "-lz"s added to the list of libraries with which to link.
Indicate in the README that "zlib" versions prior to 1.0.9 definitely
won't work.
