Subject: Unbreak devrel version checks
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=b1dbf7164ee06fa23aef5a799dd57df0357514ba;p=dbsrgits%2FDBIx-Class-Historic.git

Unbreak devrel version checks

One needs to supply the literal (string) value of a devrel to VERSION()
otherwise the checks fail. However in this case 5.8 emits annoying warnings.
Abstract the whole insanity in a neatish util function and use that.
