Here you go:
http://etr-usa.com/cygwin/mintty-icon/combined.ico
That file contains a 256 px 32 bpp (RGBA) Vista (PNG) icon plus standard
BMP icons in 48 px 32 bpp, 32 px 8 bpp, 24 px 8 bpp, and 16 px 8 bpp
sizes and depths. If you look at the directory view, you can see the
source files that went into this.
I used the icobundl tool from
http://www.telegraphics.com.au/sw/product/ICOBundle
to assemble combined.ico.
I'm willing to keep playing with this a bit more. Points of discussion:
- Do we need more sizes? I've seen reference to odd sizes like 64x64
and 96x96, but surely we can trust Vista+ to scale the 256x256 to these
sizes without needing hand-tweaked versions?
- Something I read talked about the 16x16 being 4bpp, but I can't see a
need for that since the the old Windows 95 Plus Pack days. Everything
from Win98 up should actually be fine with 16bpp and up. The only
reason I used 8bpp for the smallest ones is that's a big enough box of
crayons.
- There are two source icon files. full-size.png is pretty much what I
linked to yesterday as mintty-icon-glowy-wedge.png, with some minor
tweaks. high-contrast is a variant of this with higher contrast, needed
when scaling to smaller sizes.
- The 16, 24 and 32 px versions are pretty heavily hand-tweaked after
they were scaled down from high-contrast.png. Acceptable, or more
tweaking needed?

There are two source pieces, the fattbuttlary Cygwin icon and the KDE
Konsole icon. I assembled and massaged them on work time. Red Hat has
a copyright assignment on file for me, from way back.
