fix GCC 5.0.0 logical-not-parentheses warnings
man gcc: Warn about logical not used on the left hand side operand of a comparison. This option does not warn if the RHS operand is of a boolean type. By preferring bool over int where sensible, but without modifying any depending code, make GCC happy in cases like this, qemu-img.c: In function ‘compare_sectors’: qemu-img.c:992:39: error: logical not is only applied to the left hand side of comparison [-Werror=logical-not-parentheses] if (!!memcmp(buf1, buf2, 512) != res) { hw/ide/core.c:1836 doesn't throw an error, assert(!!s->error == !!(s->status & ERR_STAT)); even thought the second operand is int (and first hunk of this patch has a very similar case), maybe GCC developers still have a little faith in C programmers.
