Comment:

 I've removed the 10 remaining uses of `using namespace std;` from headers
 on git master in d5fb8bfde7481483e0793c08715cb84212e1b1eb, and added a
 check for this to the patch checking script to catch people trying to add
 new instances in 5a1df9067e1cd1207acee31839727955dad257b0.

 However the patch to remove the uses on master is large:

 > 33 files changed, 171 insertions(+), 168 deletions(-)

 And the 1.4 branch has nearly twice as many remaining uses - eliminating
 them all just seems too invasive a change to make several years into a
 stable release branch.

 As above, a targetted patch to address this is welcome, but I'm not easily
 able to work on one as this just isn't a platform I use.

 Unsetting the milestone for now since 1.4.18 is overdue and this can
 presumably be worked around by just specifying a lower standards version
 to the compiler.
