File cronolog-1.7.0-strncat-compilefix.patch of Package cronolog

I: Statement might be overflowing a buffer in strncat. Common mistake:
   BAD: strncat(buffer,charptr,sizeof(buffer)) is wrong, it takes the left over size as 3rd argument
   GOOD: strncat(buffer,charptr,sizeof(buffer)-strlen(buffer)-1)
E: cronolog bufferoverflowstrncat cronolog.c:336, 340
