DEF file syntax error in visual studio 2012

VERSION 3.1.4.1

DEF files are old. Back in ye goode olde days, programmers only ever needed two version numbers, major and minor. The idea of adding a revision and build number was conjured by a manager, not a programmer. A build number, wtf?

You'll have to settle for VERSION 3.1. And yes, that mistake got silently ignored for a very long time. Not anymore, the manager finally found out :)

Use a version resource instead.
