No UNIX has independence from the libc, Linux is the exception to the UNIX rule that libc is the OS API, traditionally syscalls aren't ABI stable.
This approach isn't portable to other UNIX like platforms.

Do other UNIXes have any problems similar to glibc ABI problems that Linux users experience, or do they stabilise the libc ABI similar to how Linux keeps syscalls stable?
