    [eqn]: Improve portability to Clang.
    
    * src/preproc/eqn/main.cpp: This file includes header <stdlib.h>.  As
      part of the C++ standard library, <stdlib.h> provides a bunch of
      stuff, including `atexit()`, in the global name space; it need not
      provide that stuff in the `std` name space.
    
    See <https://eel.is/c++draft/support.c.headers.other>.
