Ah, I see.
How about this?
bindgen_libclang_output=$(LC_ALL=C "$BINDGEN" $(dirname
$0)/rust_is_available_bindgen_libclang.h 2>&1 >/dev/null) \
|| bindgen_libclang_code=$?
if [ -n "$bindgen_libclang_code" ]; then
echo >&2 "***"
echo >&2 "*** Running '$BINDGEN' to check the libclang version
(used by the Rust"
echo >&2 "*** bindings generator) failed with code
$bindgen_libclang_code. This may be caused by"
echo >&2 "*** a failure to locate libclang. See output and docs
below for details:"
echo >&2 "***"
echo >&2 "$bindgen_libclang_output"
echo >&2 "***"
exit 1
fi
You can get the error code of bindgen without toggling -e.
