问题 Ubuntu 10.04.1 new theme has by default all windows background colors set to black. I don't want to change that. In Eclipse, the interface didn't change much due to 10.04.1 - except for one annoying thing: when the mouse hovers over a keyword - a variable for instance - the type (...) of that keyword is displayed in a small pop-up window.

I was surprised to find out that when examining the return value from the shell prompt I get the value modulo 256. /* prog.c */ int main(...) { return 257; } -- > ./prog.e > echo $? 1 Why don\'t I see the whole integer?
