It is saying that this C function is not mentioned in your .defs file,
for some reason. You could regenerate the *_methods.defs file and check
again. If h2defs.py really doesn't create a definition for that then you
can hand-code it in a *_others.defs file.

This is saying that you need to define a conversion in your
tools/m4/convert_*.m4 file.

This really does not seem to be mentioned in the gmmproc appendix. I
will fix that.

Again, this needs a conversion in the .m4 file.
