-ma20 -msr20 is an incoherent combination of flags: you are asking for
20-bit object sizes and 20-bit support in interrupts in an application that
uses 16-bit code and data pointers.
Use the -mmemory-model option to select a supported combination (medium is
recommended), and don't use attributes on declarations unless you need to
mix memory models (which is not recommended).
