long long a=-9223372036854775808ll;
int b=-2147483648;

test2.cpp:1:14: warning: integer constant is so large that it is unsigned

it is not.


test2.cpp:1: warning: this decimal constant is unsigned only in ISO C90
test2.cpp:2: warning: this decimal constant is unsigned only in ISO C90

huh? unsigned?



example with sizeof(int) == 4 && sizeof(long long) == 8

No, the warning is correct - is an operator and not part of the number,
