It looks to me like GCC likewise does not inline the indirection, based on a
study of the output of passing -fdump-tree-all (found this option from a
stackoverflow question).  The assembly output I was able to generate with
g++ was basically incomprehensible to me, but I didn't spend very much time
on it and I'm sure there's a way to make it at least as readable as MSVC's
assembly output, if anyone wants to try (see previous email for attached cpp
file).
