TheMagicM: I'm trying to keep classic Amiga in mind, but since MOS and classic Amiga SDK is complettely different due to copyright issues, it's a bit hard. Also since the internals of RTL changed a lot between 1.0.x and 1.9.x, and because 1.9.x compiler doesn't yet have a 68k version, it's a bit hard to keep everything in mind. But since i cleaned up as much asm code as possible, reusing the current RTL as classic Amiga RTL (or maybe even as classic AmigaPPC RTL) will be a lot easier if this ever happens.

bbrv: basic support for Altivec is in the compiler already, so as soon as MOS supports it, it will be possible to use Altivec in FPC programs.
