    Remove no-longer-needed Solaris 2.4 vfork bug workaround. · eeceac93
    Paul Eggert authored
    The workaround was for improving performance on Solaris 2.4, but
    is getting in the way now.  Emacs will still work if someone is
    still running Solaris 2.4 in a museum somewhere; Sun dropped
    support for Solaris 2.4 in 2003.
    * configure.ac (ac_cv_func_vfork_works): Default to 'no' on
    Solaris 2.4, so that AC_FUNC_VFORK doesn't think vfork works.
    * src/callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
    * src/process.c (create_process) [HAVE_WORKING_VFORK]:
    Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
    since Emacs no longer uses vfork on that platform.
