No.

gcc 2.96 is missing the <ostream> include header. <ostream.h> is still
available in gcc 3.3 (not sure about 3.4?) for backwards compatibility.

Therefore we have to use  #include <ostream.h>  and live with the
compiler warning that ostream.h is depreciated.

This has not been reverted yet (for a second time) in either 5.3 or 5.7:
 http://freegis.org/cgi-bin/viewcvs.cgi/grass/src.contrib/DUKE/r.terraflow/common.cc

the recent fixes to 5.3 were before the 5.7 copy-mix, they are the same.

I'm just about to head out to sea for a while so I can't deal with this now..
