ignore-value: prefer GCC version back through 2.0 The code didn't match the comments, so I did a bit of software archaeology. GCC 2.0 seems to support __extension__ and __typeof__, so fix both code and comments to use 2.0. * lib/ignore-value.h (ignore_value): Use __extension__ and __typeof__ for GCC 2.0 through 3.3, too.

# Run this to make 'git diff' on texinfo files give nicer hunk context:
