It used to be that "mkdir -m 755 /dev" would suc= ceed, but now it returns a "File exists" error, after which attempts to cre= ate the 'shm' and 'mqueue' directories fail and the /dev/fd, /dev/std{in,ou= t,err} links are not created. This causes some bash features to not work. T= he fix (validated on Git for Windows) would be for setups to pre-create thi= s directory outside of the Cygwin environment before running the post-insta= ll steps. See https://github.com/git-for-windows/git/issues/2291#issuecomment-5244336= 93 for the in-depth analysis. Note, this is not a current issue in Cygwin, = but is believed to become a FUTURE issue with the next release.
