// ImportC shim for the F02 resize demo (see ./app.d; copied from
// ../scaffold/c.c and extended with the xdg_toplevel fullscreen requests).
// Three jobs:
//
//   1. Import the real libwayland-client ABI *and* the wayland-scanner-generated
//      xdg-shell client glue (see ./generate.sh) into one translation unit,
//      which becomes the D module `c`.
//   2. Provide the POSIX shared-memory pieces (`memfd_create`, `mmap`,
//      `ftruncate`, `close`) the wl_shm software-rendering path needs.
//   3. Re-export the `static inline` request helpers as real `wsi_*` functions.
//      ImportC compiles static inlines but does not make them callable from D —
//      the same limitation ../../example/app.d works around by hand-expanding
//      `wl_proxy_marshal_flags`. One-line C wrappers scale far better than
//      hand-marshalling once a real window needs ~25 of them, and they keep the
//      listener types exact (no function-pointer casts on the D side).
// Nix's cc wrapper injects -D_FORTIFY_SOURCE, and glibc's fortify wrappers
// (bits/unistd.h) use __builtin_dynamic_object_size, which ImportC does not
// implement — undefine it before the first glibc include.
