Assuming you mean the following, it does not work. I still get a 4
byte enum:

#pragma options align=mac68k
typedef enum

foo  = 0x10
} fooEnum;
#pragma options align=reset

So, is gcc 4 busted in regards to __packed__ and enums, or am I doing
something wrong?

Um, I wouldn't think __packed__ to have any effect on the size of enum's.
Isn't it just applicable to struct [and maybe class] layout?

typedef enum __attribute__ ((__packed__))
{
foo  = 0x10
} fooEnum;

int main(const char argc, const char* argv) {
        printf("%d", sizeof(fooEnum));
}

and got the desired "1" instead of the default "4".

Changing foo to 0x10000000 got the result 4 again.
