This isn't really the case. fprintf is not (primarily) defined in
POSIX, but in standard C, and it is part of the standard C library
that comes with the C compiler. It is true that fprintf is not a system
call on Windows, but neither is it a system call on Unix (the system
call on Unix is write(2)).
