If you're expecting it to contain the C source code, you're mistaken.
It should just be reconstructing the CREATE FUNCTION commands.
Typical output for a C-language function might be something like

CREATE FUNCTION int44in(cstring) RETURNS city_budget
LANGUAGE c IMMUTABLE STRICT
AS '$libdir/regress.so', 'int44in';
