    build: Enable C99 support in meson.build
    
    We use C99 features (tmpl-branch-node.c), so need to explicitly
    enable them in meson.build, as some compilers will not enable them
    automatically, and will instead error when they encounter usage of C99.
    
    Further, enable gnu11, as per previous patches to other projects, where
    Christian wants to also be able to use GNU extensions. (See
    https://github.com/chergert/libdazzle/pull/10, for example.)
