avoid warning under perl 5.14

perl 5.10.1-17squeeze6 didn't give a warning for lc($someundefinedvalue).
accept floating point numbers without leading digit

(Didn't I do that already.)
handle /dev/shm being a symlink

to /run/shm (which needs to be created), from /dev being bind mounted
from the host when the host is Debian Wheezy.
