A brief comment here explaining the distinction between the three
type_ctor_* members would be helpful.  I know it is explained elsewhere
but explaining it briefly here would help people reading this code
for the first time.

Otherwise that change looks fine.

When you make the next part of it, the part that requires this change
to bootstrap, remember to modify configure.in to change the bootstrapping
test to detect this.

Cheers,
