[PATCH 2/3] libs/wine: suppress GCC12 warning (from -Waddress)

[Eric Pouech]

From: Eric Pouech <eric.pouech at gmail.com>

    GCC12 warns about testing ptr + delta against 0/NULL when -Waddress is enabled
    as it's 'most always wrong'.
    It's not wrong here :-(
    GCC docs suggests casting to (u)intptr_t to get rid of the warning
