Re: [fpc-pascal] Re: what is the FPC equivalent of Delphi's zlib unit?

I just noticed the above property is missing in FPC 2.6.2 I am porting some old delphi code to FPC and noticed it. If I simply ignore this property value (always assume it to be arNone), will it cause any problem? Dennis ___ fpc-pascal maillist -
