I don't know if this is the same issue, but there is a commit message of Oct 8, 2016 saying "epiktimer: Fix compilation for fpc3.0". Therefore you should get yourself the latest version from CCR - since for non-svn users it is a bit hard to get packages out of CCR I am attaching the zip for you. You don't mention the FPC version; this commit fixed an issue with fpc 3.0, not with 2.6.4 - and I still have a Laz 1.4.4/FPC 2.6.4 lying around, and I don't see any compilation issue of EpikTimer's demo with it.
BTW, your Lazarus version 1.4.4 is rather old. Why don't you upgrade to 1.8? It is much better, and it has the Online-Package-Manager, from which you can install third-party packages extremely easily.
