GCC 4.0 GetKeys() and BigEndianLong for Intel

I've got some code that calls GetKeys( KeyMap theKeys ) to get the modifier keys state. Then I use a mask to test which of them are down. I get a compile error:

error: no match for 'operator&' in 'theKeys[1] & 2l'

First, I know that I need to find constants for the key masks, what are those masks?

But now that KeyMap is an array of BigEndianLong rather than UInt32, the compiler can't find an operator & that works with it. What is the best way to deal with this in our new Universal Binaries world?

Also, I have a SHORT that I want to set the most significant bit on. Currently the code is

result |= 0x8000;

What's the rule of thumb to make it cross chip happy?

Thanks.
