If FreeBASIC is C90-compliant, then yes, it should work.

My design relies on something completely different.

I am sort-of dependent on the ARM syscalls being
standard, which I think they already are.

Even if they're not, I can get around that by having
a custom executable for just that non-standard device.

YOUR applications will work unchanged, because they
make NO syscalls and call NO DLLs.

That's what pdos-generic is.

Note that I tried it on 3 completely different devices
(chromebook, netbook, smartphone), and the syscalls, and
thus the applications (that don't make syscalls), all
worked fine.

Non-C90 applications can probably be made to work - C90
isn't magic - but probably require a lot of effort
setting up the required infrastructure to replace my
infrastructure.

Also, POC isn't completely complete yet. Maybe I'm
missing a concept that will be revealed later.

BFN. Paul.
