// ImportC shim for the F09 output-enumeration demo (see ./app.d and
// ../../scaffold.md). Same three jobs as the scaffold's shim — one translation
// unit for the libwayland ABI + the scanner-generated glue (xdg-shell AND
// xdg-output-unstable-v1, see ./generate.sh), POSIX shm pieces, and `wsi_*`
// re-exports of every `static inline` request helper ImportC cannot call.
// 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.
