Subject: Scanf with a long long.

I need use a 64 bit number, and int64_t is defined as a long
long.

The problem is that scanf doesn't like numbers bigger then
0xFFFFFFFF, and always returns that number in that case.  printf
works fine with them.

An example is doing this:

	long long int	i;

	sscanf("123456789", "%Lx", &i);
	printf("%llx\n%llx\n", i, i + 1);

it will print:

ffffffff
100000000

This problem seems to be reported once before in 1997, but still
doesn't seem to be fixed.
I'm using cygwin 1.3.2 on win98.


Kurt
