AC_CANONICAL_*

[Derek R. Price]

Why do the AC_CANONICAL_* functions no longer set *_alias?  There's a
FIXME comment and fixing it would be a matter of removing the 'dnl', as
far as I can see and the CVS Automake is still expecting *_alias to be
set:

# _AC_CANONICAL_SPLIT(THING)
# --------------------------
# Generate the variables THING, THING_{alias cpu vendor os}.
m4_define([_AC_CANONICAL_SPLIT],
[AC_SUBST([$1],       [$ac_cv_$1])dnl
dnl FIXME: AC_SUBST([$1_alias],  [$ac_cv_$1_alias])dnl
AC_SUBST([$1_cpu],
         [`echo $ac_cv_$1 | sed
's/^\([[^-]]*\)-\([[^-]]*\)-\(.*\)$/\1/'`])dnl
AC_SUBST([$1_vendor],
         [`echo $ac_cv_$1 | sed
's/^\([[^-]]*\)-\([[^-]]*\)-\(.*\)$/\2/'`])dnl
AC_SUBST([$1_os],
         [`echo $ac_cv_$1 | sed
's/^\([[^-]]*\)-\([[^-]]*\)-\(.*\)$/\3/'`])dnl
])# _AC_CANONICAL_SPLIT
