Patch by Mark Favas to ensure that the zlib we find is 1.1.3 or

later.  This assumes that zlib.h has a line of the form

    #define ZLIB_VERSION "1.1.3"

This solves the problem where a zlib installation is found but it is
an older version -- this would break the build, while a better
solution is to simply ignore that zlib installation.
