annotate tests/agcl/oldagsrc/pgg24.syn @ 8:ec2b657edf13
Add explicit lint-comment-style fallthrough annotations.
GCC now assumes that if you don't have these you're making a mistake,
which is annoying.
XXX: This changeset updates the AG output files only (by hand) and is
XXX: abusive - rebuilding them will erase the change. However, I need
XXX: to get things to build before I can try to get AG to issue the
XXX: annotations itself, so this seems like a reasonable expedient.
