Huh?

A filebuffer variable must be available always, so it is a global variable.
Global variables are in the datasegment. The datasegment is traditionally
divided into two parts, an initialized part (which goes into the binary) and
the uninitialized (which doesn't go in the binary).

Since the above variable is not initialized, it will not go into the binary.

Unless your platform is somehow different, but even then you can allocate it
on the heap.
