PATCH 1/1 Compile dnotify example w/o glibc 2.2 headers

<plug>dnotify is cool, check it out</plug>

If you want to compile the example in Documentation/dnotify.txt and you don't have glibc 2.2 headers installed you have 3 choices:

1) Upgrade to glibc 2.2
2) Hunt for the missing symbols in the 2.4 source tree
3) Apply this patch

Option (1) is recommended of course, but if you're lazy (like me) then...

If you're checking for glibc 2.2 or newer, better use:
#if __GLIBC__ == 2 && __GLIBC_MINOR__ >= 2
