It should probably be defined in your jamfile.
I assume that the defines are specific to gil::io.

I was planning to create a rule that is
analogous to configure.check-target-builds:

# Selects properties based on the status of a pre-built library.
# target must be a target reference which refers to
# an ac-library-target.
# true-properties will be used if the library was found
# false-properties will be used if the library was not found
rule ac.check-library ( target : true-properties * :
  false-properties * )

which you could use like this:

run test.cpp : ...
  : # requirements
    [ ac.check-library /zlib//zlib :
      <define>BOOST_GIL_IO_HAS_ZLIB <library>/zlib//zlib ]
  ;
