I tried cygwin this week and it seems to work, at least successfully building the fd binary. I've no idea of how to combine the use of cygwin, mingw32 and Linaro mingw32 cross compiler, for the latest cygwin can only install mingw64 packages. What I use is a aarch64 gcc from a porting repo of cygwin. Next we will do some functional test upon the image built on cygwin.

Thanks for all your advices.

I have no experience of this myself, but as an observer I would like
to point out that the solution I would instinctively have tried
(cygwin/mingw + Linaro toolchains for Windows) comes with non-obvious
drawbacks. The attempts to translate various filesystem properties
sometimes causes breakages.

If you have access to Windows 10,
https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux seems like
it would be much less likely to break things.

But if people otherwise use Windows-type workflows, it sounds more
useful if a solution like the one proposed by blibbet can be made to
work.

Leif
