   - Include the libws library's definitions. This library supports being included in an assembler, and provides hardware-related defines - such as I/O port names and masks.
   - Tell the assembler to emit 16-bit code; this is useful as the GNU assembler supports all kinds of x86 code, including 32-bit and 64-bit.
-  - Tell the assembler to emit 80186 code; this unlocks some additional 80186-exclusive opcodes supported on the NEC V30MZ

   - Tell the assembler to emit Intel-syntax assembly; this is entirely optional, but the examples for external assembly files in this guide all make use of the Intel syntax, as opposed to the default AT&T syntax used in inline assembly.
