Fix some cases where we're shifting a signed 1 left.
Shift 1U instead, to make sure it's unsigned; the result of, for
example, the result of shifting a signed value left is undefined if the
value times 2^{shift count} doesn't fit in the *signed* type of the
shifted value. That means, in particular, that the result of shifting 1
left by {number of bits in an int - 1} is undefined. (In *practice*,
it'll probably be -2^32, with the bit you want set, but that's not
guaranteed, and GCC 5.1 seems not to like it.)
This fixes the generator for the X11 header files; we manually fix the
header file in question, because life's too short to spend very much of
it trying to debug Perl issues that cause a
