As I might have commented before, I'm not so excited about adding and
dropping features without explicit user interaction. zlib is probably
widespread enough to assume it by default, but then the build must fail if
the library is not installed, and the user must indicate his consent by
using the --without-zlib flag. We have to be able to determine the set of
features that will be build by examining the configure command line, not
by scanning the configure output, or worse yet, by finding out that the
program doesn't behave as expected.
