He Rene,
congratulation for your newly compiled tracker on OpenWRT!
Thank you for the link to the tutorial, it is realy a good one, whitout it, the job is more difficult, or sometimes canot finish.
At the NSLU2 case, I was far best position, because I installed on it a "standard" debian linux, with native gcc packages, to compile on this system hasnot problem.
But reading this tutorial, I recall one of the problem, come up on embedded systems, with uC libs:
In the Linux Tracker Egon used long long type variables, but this type arenot exists in the uC libs. It seems, the solution is to link the special libstdc library written for ebmedded sys, with its different versions (libstdcpp libstdcxx), as you can read in the tutorial from Eric Bishop <eric[AT]gargoyle-router.com>

By the way: at the weekend was the most big radio amateur gathering in Budapest, its name is Burabu, an there are the big flowmarket, I found there a "small hill" of the Pirelli wireless router DRG A225G, with some errors. Because the most signiphicant adsl provider, T-Com use this type, and "put in the garbadge" the items, has some problems... I picked up one of it, at the first look, it seems not compatible with the previous version, DRG A125, and not compatible with OpenWrt, this modell has Infinion chips, but the previous based on Broadcom... Seems its factory-made firmware has ip6 features. But I didnod gave up now explore its features.
best:
