commit    52d01c2f52c462d29ae0fdfa44c3cae129148a6d
Author:   Andrew Dunstan <andrew@dunslane.net>
Date:     Wed Apr 27 14:09:23 2011 +0000

    Force use of "%I64d" format for 64 bit ints on MinGW.
    
    Both this and "%lld" work, but the compiler's format checking doesn't
    like "%lld", so we get all sorts of spurious warnings.
