Saluton! Bonvenon!

Maybe CPUID fails or is misdetected? Certainly people are sloppy about that, esp. for (old) non-AMD and non-Intel cpus. EDIT: Try Eric Auer's CPULEVEL tool (very small but useful).

I certainly hope not, it probably wouldn't speed up much! (EDIT: Is that intentional? Have you heard that from Juan or others? I'd consider anything DJGPP compiled as 686+ as almost a bug.)

I seriously doubt it's using those particular instructions, esp. if compiled by GCC.

Why not just point him to DJGPP's /current/v2tk/wat3222br6.zip? Although all it has is ping.exe and tcpinfo.exe (not much).

FYI: http://www.watt-32.net/

Which version, 2.18-pre?

P.S. I do seriously want to (weakly try to) rebuild Wget one of these days, for other reasons, but it's not something I feel super comfortable doing, so I haven't bothered (yet).
