-Wl,--subsystem,windows -mwindows What exactly do these gcc options do? Are they preprocessor, compiler, or linker options? Sometimes I only need -windows; sometimes I need both. How do I know when I will need both or just -mwindows? I know they are needed when creating MS Windows apps, but I'm not clear on what they are doing. Up to now, I've included these options rather mindlessly in my MS Windows apps, but I'd like to know more about them. The gcc documentation lists several "Hardware Models and Configurations" -m options, but -mwindows is not listed. The gcc documentation also states -Wl,option will "Pass option as an option to the linker. If option contains commas, it is split into multiple options at the commas," but I can't find any information on what the option "--subsystem,windows" does. Thanks for the information. Glenn Carlson
