With enabling unicode symbols 5.16 silently started allowing \0 in
symbol and package names, without any protection and further support,
which makes it unusable for me in serious environments.
Since I'm not considering cygwin a serious environment it's probably no
big deal. Unfortunately p5p and the security team is in denial and ignores
the issues involved.

I'm favoring 5.18, and started writing the patches.
It will probably be 5.18.1-1.
I found nothing critical so far.
Just minor Time::HiRes and alarm problems (we are too slow), stat,
a new regex regression, some new Storable problems.
And mainly discspace problems with my win8 64bit vm. As if 17GB is not enough.

Failed 8 tests out of 2338, 99.66% okay.

I would also favor using biber as non-packaged perl script.
Since you need so many perl deps, do you really want to keep them seperate?
I would just bundle them to something like a perl-biber-bundle
package, into vendor_perl.
