It seems that AC_VALIDATE_CACHED_SYSTEM_TUPLE has not heard of the recent
changes to the canonical system family. There are a number of problems:
(1) It should not require AC_CANONICAL_SYSTEM, only AC_CANONICAL_BUILD at
most. The rest you can handle like this:
if { test x"${ac_cv_build+set}" = x"set" &&
test x"$ac_cv_build" != x"$build"; }dnl
AC_PROVIDE_IFELSE([AC_CANONICAL_HOST],
[||
{ test x"${ac_cv_host+set}" = x"set" &&
test x"$ac_cv_host" != x"$host"; }dnl
AC_PROVIDE_IFELSE([AC_CANONICAL_TARGET],
[||
{ test x"${ac_cv_target+set}" = x"set" &&
test x"$ac_cv_target" != x"$target"; }])])
then
AC_MSG_RESULT([different])
m4_default([$1],
[AC_MSG_ERROR([remove $cache_file and re-run configure])])
else
AC_MSG_RESULT(ok)
fi
For consistency it perhaps shouldn't require anything, just issue a
warning/error if any of the CANONICAL_XXX things are called after it.
(2) The error message should contain the name of the actual cache file, as
illustrated above.
(3) The variable names have changed.
(4) Worst of all, config.guess isn't even run if the build system type is
in the cache, so you don't have anything to validate against.
If have figured out how to solve 1 - 3, but number 4 essentially breaks it
at the design level.
