~$ cat bar.c
int main() {
long long foo = 0x1100000000000022LL;
printf("foo = %lld (0x%016llx)\n",foo,foo);
}
~$ gcc -o bar bar.c
~$ ./bar
foo = 1224979098644774946 (0x1100000000000022)
~$ cat > bar.out

WFM, when I use the *correct* modifier. 'L' applies to floating-point; 
you want 'll'. Alas, this doesn't seem to be listed in 'man 3 printf'; 
looks like that should be fixed.

(Yes, I know, http://cygwin.com/acronyms/#SHTDI... maybe I will, later. 
Alternatively, can we use the Linux manpage?)
