DOS ain't dead

testing speed of DOS assemblers under djl's 8086 DOS emulator (Emulation)

Previously I seemed to omit to test two others, but today I did.

Wolfware (wasm.com) takes (estimated 8086 speed) 42 seconds under djl's ntvdm under OpenBSD. It's actually 20% slower than that if I don't remove comments and most leading line whitespace first. That's something I've not always cared about because I don't normally test under slow emulators. Just FYI.

MASM 5.10 from the MS-DOS 4 release takes 55 seconds. The link time is negligible.
