Workaround for MSVC warning that designated initializers are a C++20 feature

https://google.github.io/styleguide/cppguide.html#Designated_initializers
recommends using designated initializers as does https://abseil.io/tips/172,
but apparently they are a non-standard extension prior to C++20.
For maximum compatibility, avoid using them here.

Fixes #1413
