ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Sat Jun 23 19:21:35 2012 +0300| [145a8096d53c20da7898539e521e6d4267ab2f09] | committer: Martin Storsjö

log: Only include unistd.h if configure found it

MSVC has isatty (in io.h), but not unistd.h. (isatty isn't called
at all for windows, since there's a special case block for that.)
