You can set the desired minimal version in Xcode at compile time. FLTK, thanks to Manolo, recognizes your wish and compiles for 10.4 and up IIRC. The default setting though is 10.6 for FLTK 1.3 (again IIRC). There are few newer features we use, but there are also workarounds for older systems. As long as I don't have to dig up the Version for MacOS 8. :-)
