PUSH - a clean build went through and all my tests were ok. The current compiler (not linker) related issues are fixed (even -Os for poseidon.library)
If there are errors, check the existing issues or (re-)open one at github:

Thank you all for your interest and support - especially to the one who donated me a fair amount. That is helping me to put more effort into the good old Amiga world.
PS: Uh-Oh - found a bug^^
PPS: Ok - pushed also a fix for this. All good! Yes? No?
