Hi all,

when building the latest master on macOS with --with-xwidgets, I get
this warning:

--8<---------------cut here---------------start------------->8---
xwidget.c:492:17: warning: variable 'f' set but not used [-Wunused-but-set-variable]
  492 |   struct frame *f = NULL;
      |                 ^
--8<---------------cut here---------------end--------------->8---

This is with:

$ gcc --version
Apple clang version 17.0.0 (clang-1700.6.3.2)
Target: arm64-apple-darwin24.6.0
Thread model: posix

Best, Arash
