I don't think making it work as I suggested is critical for GCC 9 in comment
#0.  I noticed it while testing the new -Wattribute-alias/-Wmissing-attributes
options with Glibc, but (AFAICT) Glibc doesn't actually depend on the inlining
attributes for aliases working this way.

It would make sense to me to issue a warning for this use case until it is
implemented (if it ever is).
