Works fine here:

    $ gawk --version
    GNU Awk 5.0.1, API: 2.0 (GNU MPFR 4.0.2, GNU MP 6.1.2)

    $ cat one.awk
    function f1(n1) {
       return n1 + 10
    }

    $ cat two.awk
    @include "one.awk"
    BEGIN {
       print f1(20)
    }

    $ unset POSIXLY_CORRECT
    $ gawk -f two.awk
    30

Finally, I would make a suggestion. "@include" is not POSIX, so if you find
yourself relying on something like this more and more, it might be better to
switch to a proper programming language. Something like Perl, Lua or Tcl.
