I can xfail them with:

// { dg-do run { xfail { ! { dg-require-cxa-atexit } } } }

The only problem with this is that it doesn't allow me to paper over the
other problem with init18.C, namely that it calls _Exit.  HP-UX doesn't
have _Exit(), which is a C99 routine, and not a C++ routine.

I could call _exit(), but if I do that, can I put in a declaration for
_exit() in the test?  I am worried that some platforms might have a
declaration for _exit() in stdlib.h and might complain about duplicate
definitions.  I could remove the include of stdlib.h and do explicit
declarations for exit, _exit, and abort....

Any suggestions for handling _Exit()?
