#1519 Incomplete ms_printf format

[Arseny Klimovsky]

"%lld" is a valid specification for printing long long int variable since MSVCRT8.0
See documentation: http://msdn.microsoft.com/en-us/library/56e442dc%28v=VS.80%29.aspx
It is tested, that it really works.

MinGW version 4.5.2 issues a warning for such usage.
See code example in bug http://sourceforge.net/tracker/index.php?func=detail&aid=1963136&group_id=2435&atid=102435
