That's amazing news.

But an old bug crept in:
H is NFS file system
$ uname -a
CYGWIN_NT-10.0-19045 bastille0x44ef 3.5.0-0.423.g7ced682549ae.x86_64
2023-09-07 17:19 UTC x86_64 Cygwin
$ mount
C:/cygwin64/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin64/lib on /usr/lib type ntfs (binary,auto)
C:/cygwin64 on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
H: on /cygdrive/h type nfs (binary,posix=0,user,noumount,auto)
M: on /cygdrive/m type nfs (binary,posix=0,user,noumount,auto)
N: on /cygdrive/n type nfs (binary,posix=0,user,noumount,auto)
O: on /cygdrive/o type nfs (binary,posix=0,user,noumount,auto)
P: on /cygdrive/p type nfs (binary,posix=0,user,noumount,auto)
$ cd /cygdrive/h/tmp/
$ mkfifo f1.fifo ; echo $?
0
$ mkfifo -m 0600 f2.fifo ; echo $?
mkfifo: cannot set permissions of 'f2.fifo': No such file or directory
1

So chmod() for a FIFO inode on NFS fails. Tested with MSFT NFSv3 and
new builds of the NFSv4.1 ms-nfs41-client filesystems.
