No, that's not it; the discussion is definitely about that code being
compiled x86 where those extensions are relevant.

The example machine language disassembly listing actually shows two
copies of the generated code, which are being called according to the
two different convntions, and access the argument accordingly: the
fastcall generation gets it from a register, whereas the stdcall gets it
from the stack.
