Good job! It means you can compile this GCC version on any system with a working ANSI-C compiler!? That's real portability, and that's how it should have been done from the beginning. Congratulations!

What about the Amiga 1000? Kickstart is not in ROM. How are the sectors of a floppy disk read without Kickstart being available?

There is a small Boot ROM, which can do nothing else than loading 256K of a kickstart disk into the WOM (Write-Once Memory).
You can use it to load your OS instead, but afterwards you still have to do everything yourself.
