ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Wed Jul 29 23:08:09 2015 +0300| [bf0cef5c3a114df452e5476167634dd8f51eb448] | committer: Martin Storsjö

checkasm: Include io.h for isatty, if available

configure does check for isatty, and checkasm properly checks
HAVE_ISATTY, but on some platforms (e.g. WinRT), io.h needs to be
included for isatty to be available.
