Hi!
gengtype has an option '-d' which allows to dump it's internal state. I planned
to use it in order to create some kind of list of all data which GCC stores in
garbage-collected memory.
Unfortunately this option was broken. The attached patch fixes it. Because it
only affects gengtype's internal debugging option (and is also rather small), I
think it's OK to commit it without approve (as obvious).
Bootstrapped and regtested on x86_64-pc-linux-gnu.
