Re: [9fans] another compiler bug (another try to send this coherently)

["Boyd Roberts" <boyd@fr.inter.net>]

do you define implementation as the compiler or the
whole system?  the other guy seems to be doing stupid
stuff with APE or some ANSI (ie. non native plan 9
compiler [ken C]):

#include <stdio.h>
#include <stdlib.h>

int
main()
{
static unsigned char tab[1] = { 0x80 };
static int x = 0x80;

printf("%d %d\n", tab[0] << 24 >> 31, x << 24 >> 31);
exit(EXIT_SUCCESS);
}

why he just can't read the doc and stop fucking with stupid
shifts is beyond me?  is this C programming 101?

i would class the compiler as the implementation, 'cos
you could have multiple compilers (and you do) on plan 9
or on some random unix you could have the native compiler
and then install gcc (god forbid).

i tend to err on the side of caution (ie. paranoia/overkill)
so i don't bitten by such glop.
