MSVC apparently requires this for warnings in the range 4700-4999. https://docs.microsoft.com/en-us/cpp/preprocessor/warning?redirectedfrom=MSDN&view=vs-2019 PiperOrigin-RevId: 285516232 -- 4a060cbeda76e89693c50276ae5b62cbf0fff39a by Derek Mauro <dmauro@google.com>: MSVC: Fixes uniform_real_distribution_test in opt mode Disables a constant arithmetic overflow warning in a test that tests the behavior on overflow. This should be tested because a user might have this warning disabled.
