I know. I did once. And I don't want to do it again! :o)

Let's say I want to use the O_DIRECT feature with files. Of course O_DIRECT is
not defined in 2.4.4 but in 2.4.19.

So would it be enough to define the flag O_DIRECT in my application?
Since all that glibc does is passing the flags to the kernel while opening a
file, doesn't it?
