As I did try this, I'll show it too... ;-P

md5sum ok.

Is this to get a reference on the speed difference "cygwin vs native"?
Hmm... it has no GUI, so it is "cmd" version, if anything :-)
(Though there seems to be separate gui frontends available)
All prebuilt binaries are from 2001.
Just as the source; it seems to have been stale since then.
Same P2/450 again - as always:

The output is exactly the same amount of bytes.
But md5sums differ on three of the mp3's.
Probably due to diffrent "c.o"++

Answer: Approximately 20-40% faster in "cmd native mode"
IMO the better "compatibility" with the other cygwin tools is worth more
than the extra speed. This of course reflects that I mostly encode my own LP
records, at most one per week. For archiving - and to be able to create CD
copies for my personal use. (I see the LP's as "collectors items" - i.e. I
use them as little as possible).
Hmm... As I looked for that prebuilt binary I found a DLL version of the
encoder. I wonder what difference it would make to have a cygwin "frontend"
based on that...
Well, I think I'll let that be a future project.
