But that is only a partial fix.  The problem is not limited to Solaris
2.5 and later: it will also occur on earlier Solaris versions, and I
think it'll occur on other hosts as well.  The more general problem is
that Emacs sometimes uses vfork without defining HAVE_VFORK.

One way to fix the more general problem would be to use the
AC_FUNC_FORK of Autoconf 2.51 and later.  It defines a macro
HAVE_WORKING_VFORK that Emacs could use instead of HAVE_VFORK.
