    c: Avoid clobbering TREE_TYPE (error_mark_node) [PR99990]

    The following testcase ICEs during error recovery, because finish_decl
    overwrites TREE_TYPE (error_mark_node), which better should stay always
    to be error_mark_node.

            * c-decl.c (finish_decl): Don't overwrite TREE_TYPE of
            error_mark_node.

            * gcc.dg/pr99990.c: New test.
