I have been VERY happily pleased about how well Cygwin runs using
Prism on Windows/ARM64. I can build and test my x86_64 code there using it
despite the underlying CPU being an ARM. My genuine Windows/x86_64 machine
is not that new these days. Using a stack Macbook-m1/UTM/Windows11-ARM64
runs the proggrams in build using cygwin on that Windows as x86_64 code via
Prism and is quite close in speed to that which I observe on my "real"
Windows computer.
If there was both an ARM64-targeting cross compiler and a bunch of
libraries I would be using it to provide the bash shell, autoconf etc that
I want to use to build native ARM applications there. Well I can
invoke and ARM64-targeting clang from cygwin there or Microsoft's
compiler and I am fully expecting that "vcpkg" will let me get a very
large proportion of the rest that I require in place, but I have not
played that game yet.
So in the sense "can it provide part of a development environment on a
fast Windows-on-ARM machine" it is not too bad, but things may take a bit
of fudging and it will depend on exactly what you want to do.
For building and running Linux-style software on Windows/ARM64 you can of
course fire up WSL there which gives you a genuine Linux world, but at
present using that to cross-build for native Windows/ARM64 is something I
have not found good pointers about.

Greetings!
What is the current status of Cygwin on Windows/ARM64? Does it work?
