[9fans] UTF and the preprocessor

[hugo rivera]

Hi there,
I just found out that the preprocessor on plan 9 doesn't like utf. I
hope I am wrong, but just try to compile something like

# include <u.h>
# include <libc.h>

# define ΓVAL 12

void main(void);

void
main()
{
        int β;

        β = ΓVAL;
        while(β < 15)
                print("%d\n", β++);
        exits(nil);
}

and you get a "syntax in #define" error that points to the define
line. Remove (or replace) the utf character and everything works as
expected.
