This makes a code a bit more clear and also gets rid of C4146 warning
on MSVC compiler:
 'unary minus operator applied to unsigned type, result still unsigned'.

In case uint64_t variable is initialized or compared against -1U
expression which corresponds to 32-bit constant, UINT_MAX macro
is used to preserve NFC semantics.
