The official OS name is "cc65" (at least I hope so:-). Currently I'm using it
only for cc65 modules.

This is up to André to decide. When generating cc65 modules, ld65 adds a 16
bit word as OS data, which can be set using ID=xxx in the linker config. So
another possibility would be to use this ID to distinguish your modules from
loadable cc65 modules. This would need a small change in the linker, because
currently no exports and imports are allowed when generating cc65 modules. For
example, I could allow exports and imports for ids >= $8000, so you could use

        os = cc65, id = $8000, type = small;

for your modules. Since this is nothing more than just another id, so you can
also talk to André to register your own OS id. But even this would need
changes in the linker, because it does currently not allow other than the
three known ids.

Of course you can also ignore the whole issue, and just use the Lunix or
OS/A65 ids:-)

I'm still fighting:-) Seriously: While it would be possible, it doesn't make
sense. The 64 bit integer type and a complex floating point type is just too
much for an 8 bit machine. Actually, this is one of my biggest objections: The
standard is no longer suited for small machines. And since the C99 standard
declares all older C standards void (the C89 standard is actually no longer an
official standard), most compilers for small machines won't be standards
compliant.
