# Using the System library

You can link the system library SYS.A to your application if you don’t want that your application uses rsxnt.dll. The size of your application will grow by 15-25 KB. The advantage is the you only need the EXE-file to run the application.

Dual-mode requires the -Zwin32 switch. Dual mode programs are not supported with the system library.

Example:

    	gcc -Zwin32 -Zsys test.c
