Yes, I should have said so:

    tjaden@xxxxxxxxxx ~ $ cat t.c
    #define PAL_SIZE 256
    typedef struct RGB { unsigned char r, g, b, filler; } RGB;
    typedef RGB PALETTE[PAL_SIZE];
    void foo (RGB *pal);
    void foo (RGB pal[PAL_SIZE]);
    void foo (PALETTE pal);
    void foo (RGB *pal) { }
    int main (void) { return 0; }
    tjaden@xxxxxxxxxx ~ $ gcc -W -Wall -Wno-unused -ansi -pedantic t.c
    tjaden@xxxxxxxxxx ~ $ mv t.c t.cc
    tjaden@xxxxxxxxxx ~ $ gcc -W -Wall -Wno-unused -ansi -pedantic t.cc
    tjaden@xxxxxxxxxx ~ $
