Yup: autoconf 2.59.

No need to include generated files in the diff.  They only add clutter.
 Did you regenerate it with autoconf 2.59?

"Define if you want operations on GIMPLE (the basic data structure of
the high-level optimizers) to be checked for dynamic type safety at
runtime.  This is moderately expensive."

The rest looks fine.  Little by little we can convert the GIMPLE
optimizers to use 'if defined ENABLE_GIMPLE_CHECKING' wherever
ENABLE_TREE_CHECKING or ENABLE_CHECKING are used.
