mozilla-central/netwerk/protocol/websocket/nsWebSocketHandler.cpp:966:36: error: cast from 'PRUint8*' to 'long unsigned int' loses precision [-fpermissive]

That's because long is 32-bit on win64. In this case we don't care about losing precision, but it's still an error for GCC. The fix is as simple as using uintptr_t.

Could you cast to some PRU*** type?

Or, uintptr_t could be ok, but this is Patrick's code

fix using PRUptrdiff

The attached patch uses PRUptrdiff instead of uintptr_t. Please choose preferred version.

Jacek, what do you think about using PRUptrdiff ?

There are a number of places in the code base (netwerk is not one of them) that go to some length to make sure uintptr_t is defined for old platforms.
