autoconf bug report (from ./configure for proftpd.org)

[Brian Dickson]

On FreeBSD system, got the following message running configure script
included with very recent proftpd (1.2.8 release version):

configure: WARNING: sys/mount.h: present but cannot be compiled
configure: WARNING: sys/mount.h: check for missing prerequisite headers?
configure: WARNING: sys/mount.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------------------ ##

(Just FYI, no need to reply to me.)
