Thanks.  The bug is actually in lang/c99/mach.scm.  c99act.scm is output from running make-lalr-{spec,machine} on mach.scm,

    (jump-statement			; S 6.8.6
     ("goto" identifier ";" ($$ `(goto ,$2))). ;; <= was `(goto $2)
     ("continue" ";" ($$ '(continue)))
     ...

Also, I am currently working on the fixes branch to cleanup the C-preprocessor support so that #:mode ‘code works more robustly.
