   GCC 14+ makes an error:
       lua-5.4.4/src/ldo.c:66: error: implicit declaration of function
       '_longjmp'; did you mean 'longjmp'?
   (wireplumber bundles Lua, which uses them under LUA_USE_POSIX.)
   The distinction from setjmp/longjmp is the signal mask, which relibc's
   implementation does not save in either form, so the alias is accurate. */
