Last release was 2014. Project is still hosted on SourceForge. Website copyright notice ends in 2018. Last commit to the github repo was 2018. Project front page mentions the original Xbox, Minix, and Zaurus (and early 2000s Japanese handheld organizer that ran Linux) and Solaris as targets.
This should give you some idea of what time frame to view any claims from the website in.
I don't see that as negative, but a remark that most younger people are not used to the look of Windows up to (and including) 2000. And the last time I personally used FLTK had been around 2000 too. Which, btw, (at least back than) looked more like Irix' 4DWM controls than Windows.
