You can't know at compiletime of your unit whether the program that will
use it will use {$apptype gui} or not. You can check it at runtime thoughm
there's a global boolean variable in the system unit that's set to true. I
don't know whether it's public not the name, but if you compile a program
using the -a option, you should be able to see the name in the generated
assember code (the first instruciton of the main program sets the apptype
variable)
