When operating system starts application, it lookups special description table in EXE file called IMAGE_OPTIONAL_HEADER. This structure contains so called Subsystem field. When Subsystem is IMAGE_SUBSYSTEM_WINDOWS_CUI - OS attaches console window to this process. Otherwise, console window will not be added.

Compilers/linkers usually have parameters to set output application subsystem type, e.g. when you link your code using Microsoft Linker you can add /SUBSYSTEM:WINDOWS parameter and you will not see console window when starting your application.

The other way: compiler may automatically decide to set EXE subsystem to Console when seeing main function in your code, or set GUI subsystem when you have WinMain as entry point.

About TCC: I see -Wl,-subsystem=gui option in TCC documentation, but seems it is not worked. So try to send a bugreport or use more mature compiler/linker.
