Hi, SVN r6290 brought llrint(), but that function is not defined in Cygwin (because it uses newlib for math.h). I found this LGPL code that defines llrint() as inline for x86: http://sourceware.org/ml/cygwin/2002-12/msg01146/mathinline.h Would it be acceptable to copy that llrint() implementation into libavcodec/i386/mathops.h ? Regards, V?ctor
