Compiler Option: -s
Sets the executable subsystem
Syntax
-s < subsystem >
Parameters
subsystem
The executable subsystem: gui or console.
Description
The -s compiler option specifies the executable subsystem. Allowed subsystems are gui and console (by default, console is used). Specifying a gui subsystem prevents the console window from appearing behind the program window.
The intrinsic macro __FB_GUI__ is set to non-zero (-1) if GUI subsystem mode is active, and set to zero (0) otherwise. #Pragma Gui and #Pragma Gui = 0 provide the source-level form of the same setting.

Platform Differences
- On Windows and Cygwin, this controls the linker subsystem.
- Other targets may use the same mode value for target-specific startup or runtime behavior.
