Thanks, i'll push it during the weekend.

I've fed gfortran.h into the script and found some CLASS_DATA spots,
see attached bootstrapped and tested patch.
Do we want to have that?
If so, i'd write a proper ChangeLog, of course.

Thanks!

Thanks, i'll push it during the weekend.

see attached bootstrapped and tested patch.
Do we want to have that?

Some of it makes sense, but not all of it.

It is a macro to access the _data component of a class container.
So for class-related stuff it makes sense to use CLASS_DATA, and 
typically there will be a check that the type is BT_CLASS before.
But for cases where we loop over all of the components of a type that is 
not necessarily a class container, it doesn't make sense to use CLASS_DATA.


So I suggest to only keep the following hunks.

I have left these subfunctions alone for now to get the other hunks out
of the way. I have adjusted the patch according to your other comments
and pushed it as r14-973-gc072df1ab14450.
