Since it's critical for Gentoo gawk, perhaps they didn't want to depend on
gawk's source distribution suddenly removing that file or otherwise
changing (and patches need to be maintained up-to-date against the
original, while a standalone file does not need maintenance).
But this is all just my guessing.

How are you building it? It needs special commands because it needs to
become a shared object, not an executable.

Note that building that file is by no means necessary for a working gawk.

And, even if you built it, it wouldn't do anything unless you specifically
used the extension() gawk command to reference the object file and import
the extra definitions (see the link I posted in the first email for all
the gory details. Also the Makefile that comes with Gentoo's own
filefuncs.c may help).
