I wonder if there's a possible workaround to make that less intrusi= ve? Try if C:\Windows\Sysnative\drivers\etc works. That should be the easiest way to fix the issue in the script. > The error message implies that it may have computed the wrong directory, > which it hasn't - it's just that the directory doesn't exist. >=20 > The other is that all Cygwin binaries are emitting the "Could not compute > FAST_CWD pointer" warning. Nothing we can do about, unless somebody dives into assembler code on such a system. If the code switches to ARM64 early, this could be tricky. As a workaround I pushed a patch to check for running in WOW64 under ARM64. The warning is skipped then. The already existing fallback code should work most of the time. Just give the latest developer snapshot from https://cygwin.com/snapshots/ a try.
