annotate lib/mountlist.c @ 928:ff6a703d860e
(read_filesystem_list): Add `|| defined (__OpenBSD__)'
to the NetBSD #if so OpenBSD also uses the f_fstypename member.
(fstype_to_string): Add `&& !defined (__OpenBSD__)' to the NetBSD #if
expression to exclude this function definition. OpenBSD 2.1 beta
doesn't need it. Patch from Hugh Daniel <hugh@ecotone.xanadu.com>
