Not sure about that. Tried it from cli using several different incantations of 
--includedir and --oldincludedir such as; /, /usr, /usr/include and that 
warning persisted. I think it has something to do with their configure script.

So for a fstab like this;

# /etc/fstab: static file system information.
# <file system> <mount point> <type> <options> <dump> <pass>

# proc is required pretty much on any linux system except embedded systems:
proc    /proc           proc    defaults        0 0

# shmfs is surpassed and obsolete
#shm    /dev/shm        shm     defaults        0 0
none    /dev/shm        tmpfs   defaults        0 0

# devfs and devpts are not friends, yet 2.6 needs devpts:
devpts  /dev/pts        devpts  defaults        0 0

# usb devfs can be helpfull on interactive (desktop) machines
#usbfs  /proc/bus/usb   usbfs defaults       0 0 

# /tmp should be wiped on boot so by default it helps to have it on tmpfs
tmpfs   /tmp            tmpfs   defaults,size=2048m,nr_inodes=64m       0 0

# /var/lock and /var/run need to be clean on reboot:
tmpfs   /var/lock       tmpfs   size=4m 0 0
tmpfs   /var/run        tmpfs   size=4m 0 0

# /var/tmp should NOT be on tmpfs, LSB states that the contents of it must 
# stay intact on reboot
#tmpfs  /var/tmp        tmpfs   size=32m        0 0



UUID=a26179bd-93de-4f4a-bffc-d22fab04614c       /       ext4    defaults        
0 0
UUID=a883786d-56c2-48a8-af33-31d3c1e88761       swap    swap    defaults                
0 0

Get rid of everything except for the last two lines?

Not sure why that should or needs to be left for the user to correct.
