My bad, csih_old_cygwin works as documented.
But there is a bug in csih_use_file_etc:

$ cat /etc/nsswitch.conf
# /etc/nsswitch.conf
#
#    This file is read once by the first process in a Cygwin process tree.
#    To pick up changes, restart all Cygwin processes.  For a description
#    see https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch
#
# Defaults:
# passwd:   files db
# group:    files db
# db_home:  cygwin desc
# db_shell: cygwin desc
# db_gecos: cygwin desc

This is not working correctly:

   if [ ${use_file} -ne 0 -a -f /etc/nsswitch.conf ]
   then
     grep -Eq "^${file}:" /etc/nsswitch.conf &&
       grep -Eq "^${file}:[^#]*\<db\>" /etc/nsswitch.conf ||
        use_file=0
   fi

$ grep -Eq "^${file}:" /etc/nsswitch.conf && grep -Eq 
"^${file}:[^#]*\<db\>" /etc/nsswitch.conf || echo foo
foo

I don't think that's what you want.  Both of the greps are false 
(returning 1) and use_file is being set to 0.
