Hi Aleks.
Seems that PDF_STM_FILTER_FLATE_DEC and PDF_STM_FILTER_FLATE_ENC are only defined when libz is available (HAVE_LIBZ defined). As this is an optional feature, compilation shouldn't crash if libz not available (as in typical mingw compilation). The following patch fixes the issue disabling the corresponding UT when libz is not available. Applied, thanks. To this means that you were able to run the unit tests in wine? :)
