Is the definition in xterm_io.h not working?

This is true for musl, not for glibc.

The handling of _POSIX_SOURCE and _POSIX_VERSION differs between musl 
and glibc due to glibc supporting older POSIX versions, and glibc also 
supporting developers of portable code to select some specific older 
POSIX version.

So this was caused by musl not supporting older versions of POSIX,
where _POSIX_SOURCE was part of the standard.

The proper fix would be an autoconf test for setsid().
