It is an external reference amiga.lib depends upon (an "xref" for the fans of assembler), and something the binary has to provide. Thus, typically, the symbol is provided by the compiler startup code ("c.o"), there filled in, and picked up by the amiga.lib for performing the system call. The amiga.lib is part of the AmigaOs SDK, even though it is rarely needed nowadays.

I don't know if that is the same format that SAS/C accepts,

SAS/C is a C compiler, but it is accompanied by asm, a 68K assembler. It accepts "mot" syntax, that is the syntax that is described by motorola in the "Family guide". Be warned, the arguments of "cmp" are the other way around, i.e. "cmp" is as "sub", with the target at the right-hand.

I don't think why it wouldn't, after all, Linux also has support for affs, and RDB, the "Amiga variant of MBR".

All the details, of course, and this sounds more like a work plan for the next years to come, of course...
