ISO C++17 does not allow 'register'

Was trying to build osquery on ubuntu vm. User the followed instruction: https://osquery.readthedocs.io/en/stable/development/building/

While building there is an error:

/home/user/osquery/osquery/sql/sqlite_string.cpp:234:55: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
      sqlite3_result_int64(context, (__extension__ ({ register unsigned int __v, __x = (in4->sin_addr.s_addr); if (__builtin_constant_p (__x)) __v = ((((__x) & 0xff000000) >> 24) | (((__x) & 0x00ff0000) >> 8) | (((__x) & 0x0000ff00) << 8) | (((__x) & 0x000000ff) << 24)); else __asm__ ("bswap %0" : "=r" (__v) : "0" (__x)); __v; })));

Found, that C++17 is no longer support "register" as class specifier, so it should be removed in tergeted file.

By looking into sqlite_string.cpp, there is only one match: "void registerStringExtensions(sqlite3* db)", and no no specified lines.

There is line 234 followed file sqlite3_result_int64(context, ntohl(in4->sin_addr.s_addr));

How can i fix this?

Thank you!
