What does an g++ option "-mwindows"

[Youda008]

Hi.
Can you explain me, what a g++ command line option "-mwindows" does? The CodeBlocks adds it to the flags when compiling a project for some reason, and the application then won't start properly. When i write a custom Makefile, delete this option and build a project with it, application works.

CB adds it because certain types of targets needs the option to run or build correctly.

Oh sorry. I have been trying to find out for whole afternoon, why my application does not starts properly and only runs on background using 1 whole core. Google showed nothing on many pages, I've almost gone berserk, and forgot to use the forum search.

Edit: Now with the help of other threads i found, that my project has type "GUI application". I have no idea how it got there, but setting it back to "Console" solves the problem.
