Yeah, we're *not* doing that.  There are definitely places where
ereport/elog are used with nonconstant elevel.

It's curious though that MSVC fails to notice that the variable never
changes.  I wonder whether we could get away with changing the elog
macro to do     const int elevel_ = (elevel);
as ereport does, and whether it would help if so.
