By working with both kinds of dumping while working on the garbage
collector last year, and then the MS-DOS port earlier.  I didn't
hesitate to assume:

#ifdef HAVE_UNEXEC

#else

#endif /* HAVE_PDUMPER */

My mistake, sorry.

BTW, what I said about `configure' still stands.  Count the number of
AC_ARG_WITHs that don't print errors if the package they are supposed to
enable is not present.
