The minimal fix is the other one, to change the headers to <*.h>, as none of
the calls to library functions in the file are std::-qualified. :) Alright,
I'll send a patch for that once I'm able to test that the same problem is s=
till
present on master and that the same fix is sufficient to get things working=
