Fix an integer overflow warning
    
    Recent GCC versions emit warnings like this during compilation:
    
    <source>:10:31: warning: integer overflow in expression of type 'int' results in '-2147483648' [-Woverflow]
       10 |   const uint32_t limits[] = { -minInt, maxInt };
          |                               ^~~~~~~
    <source>:10:31: warning: narrowing conversion of '-2147483648' from 'int' to 'uint32_t' {aka 'unsigned int'} [-Wnarrowing]
    
    And clang even treats them like an error.
