It's POSIX, and they're not deprecated.  POSIX specifies that open() and 
dup() returns the lowest available integer, and of cource FILENO_STDIN 
== 0, FILENO_STDOUT == 1, FILENO_STDERR == 2.

I ended up having to implement POSIX-style file descriptors, after all; 
the main reason was that newlib apparently expects that file descriptors 
fit in a "short" :(
