It passes everything that followss (up to a space, perhaps) to the linker, 
so you have to look at the linker's usage to find out what all those flags 
do.

In this case, /exet:nt means "EXEType: Windows NT" (i.e. XP), 
/su:windows:4.0 means "SUbsystem: Windows 4.0" (i.e. XP again, unless 
someone really pedantic wants to tell me otherwise).  So it's telling the 
linker we want to make a Windows executable.  This will prevent any command 
prompt from flashing up when your EXE starts, or something like that.
