This is fixed for NTFS, but still broken for Windows builtin NFS v3 client:
$ mkfifo -m 0600 hellofifo.fifo
mkfifo: cannot set permissions of 'hellofifo.fifo': No such file or directory
$ ls -l hellofifo.fifo
lrwxrwxrwx 1 Unix_User+3640 Unix_Group+3640 11 Aug 18 05:58
hellofifo.fifo -> ':\0:c4:1180'
$ uname -a
CYGWIN_NT-10.0-19045 wincluster01_40_88 3.4.8-1.x86_64 2023-08-17

Thanks,
