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.
