VC 1.52 uses "external" constants _AHINCR and _AHSHIFT, that work for both real-mode and protected-mode ( assuming that the protected-mode OS uses "selector tiling" for blocks > 64 kB ).

The -Fa option generates assembly code, but without "red tape" cmds, so the generated code has to be adjusted before feeding the assembler with it.
