I was afraid (but I am not surprised) of such a reply.
So won't spend any additional minute on patching gengtype.
So I will have to generate some additional file in MELT (containing 
simply the
      typedef gimple* melt_gimpleptr_t;
line) and hack the build procedure.

What exact functions (their name, the source files defining them) in the 
current GCC trunk are you referring to by your "introspection" word? 
Last time I checked (a few months ago) there where nothing related to 
that. Today, the only occurrences of introspection (in GCC trunk svn 
rev233268) are in Java part and in the libsanitizer.

Regards.
