The semantics for @include are different between igawk and "native" gawk
@include (since 4.x).  The newer gawk versions treat @include statements
like they would treat the --include option on the command line.  In
particular that means that each include is processed only once and you
should (only) use it to define functions.

The igawk script was removed from gawk in this commit

http://git.savannah.gnu.org/cgit/gawk.git/commit/?id=577ece63770a6c4b5ad00d6998127fb7e85b86b9

but left in the manual, so you can resurrect it either from there or
from Git:
