[PATCH] Fix two undefined behaviors in gcc sources

Hi! --with-build-config=bootstrap-ubsan on i686-linux showed most often these two issues. The first one is that 32-bit signed time_t is multiplied by 1000, which overflows the int type. The result is then cast to unsigned, so even on 64-bit hosts we don't care about the upper bits. The other ch
