Isn't it?

Comment from emacs source:
     Use pathconf with _PC_CASE_INSENSITIVE or _PC_CASE_SENSITIVE if
     those flags are available.  As of this writing (2019-09-15),
     Cygwin is the only platform known to support the former (starting
     with Cygwin-2.6.1), and macOS is the only platform known to
     support the latter.  */
