Another typo :

program p
print *, [character((100)) :: 'x']
print *, [character((1,0)) :: 'x']
end
$ gfortran-6 z2.f90

print *, [character((1,0)) :: 'x']

I compared this with clang.
1) typedef int token;
Both GCC and clang optimize this to a single jump.
2) struct token {int a};
clang optimizes this into a single jump. GCC generates:

For clang, this seems based on size: up to size 16 they get jmp, starting from
17 they get a call.
For gcc, we give up on anything more complicated than a "register":

Not sure, as I've been off pure-type computations for a while now. Looking at

Well. Here it is using a vector register (v31) as the iterator reg,
which we do not handle. Should we? Where does it come from?
