Do you think that we could raise the minimum C standard on WIN32 to
C11, at least for MSVC?  There is a patch floating around to add
pg_attribute_aligned() and perhaps pg_attribute_noreturn() for MSVC:

noreturn() needed at least C11:

Perhaps we'd better also bump up the minimum version of MSVC
supported..
