These warnings occur when building wdiff 1.2.2 with a modern version of
clang:

deprecated in all versions of C and is not supported in C2x

Once compilers start compiling in C2x mode by default, this will be a problem.
Maybe you could fix these issues and release a new version of wdiff before
that happens.
