Make that:

    int main(void) {

You can't do sizeof(enum) for the same reason that you can't do
sizeof(struct) or sizeof(union).  It just doesn't make sense.
Try using sizeof on a particular enum and it will work.  In DJGPP,
the size will be 1, 2 or 4, depending on how many values the enum
has and whether or not you compiled with -fshort-enums.

By the way, your code also assumes that it's OK to print a size_t as
if it were a long.  This will work in DJGPP, but you should cast it
to be safe (and use unsigned long rather than long).
