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 KeyPgDdfbgui__FB_GUI__ is set to non-zero (-1) if GUI subsystem 
	mode is active, and set to zero (0) otherwise.  KeyPgPpPragma#Pragma Gui and 
	KeyPgPpPragma#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.
