The BLKFLSBUF and FDFLUSH ioctls are Linux specific, and do not
really have anything to do with __GNUC__ (which is also used on
OS/X and Solaris).  Only print these warnings on Linux systems.

statfs64() is deprecated on OSX and generates a deliberate warning.
Fix some other warnings that show up on OSX builds.
