hi,
nevermind about recompiling.... i've made every error (except the memory 
allocations) to warning with the below change:
https://github.com/rare-freertr/freeRtr/commit/a59b34ecaa14ad276267cb0f5542678c219b0d71
as far as i know the fedora is daily rebuilds itself automatically, so just 
wait a day and upgrade afterwards...
br,
cs
