I cannot reproduce this with

  GNU Awk 5.3.0, API 4.0, PMA Avon 8-g1, (GNU MPFR 4.1.0, GNU MP 6.2.1)
  Copyright (C) 1989, 1991-2023 Free Software Foundation.

running on

  Linux maintain0p.gnu.org 5.15.0-113-generic #123+11.0trisquel30 SMP Wed Jun 
26 05:33:28 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

I get 4, as expected.

So I presume this is specific to the Cygwin port of Gawk, and suggest
to take this up with the maintainers of that port.
