There are a few ways to fix this warning. If you really need a
positive number, just add an \samp{L} to the end of the literal. If

clearest to start with all bits set and clear the desired upper bits.
For example, to clear just the top bit (bit 31), you could write
-\code{0xffffffffL {\&}{\textasciitilde}(1L<<31)}.
+\code{0xffffffffL {\&}{\textasciitilde}(1L<{}<31)}.
