When --enable-libstdcxx-pch is used the <bits/extc++.h> header breaks the build because of these narrowing errors. libstdc++-v3/ChangeLog: PR libstdc++/105681 * include/ext/pb_ds/detail/resize_policy/hash_prime_size_policy_imp.hpp: Limit ga_sizes array to values that fit in size_t. * include/ext/random [__SIZE_WIDTH < 32] (sfmt86243) (sfmt86243_64, sfmt132049, sfmt132049_64, sfmt216091) (sfmt216091_64): Do not declare.
