I guess the way it breaks it is that I can't use 2021b api in my program because it
does not compile. I have since reverted back to 2021a. I can build gretl 2021b from source
and it works without any problems it is only when I try to use it in the program I am
writing.
I think the problem might be that libgretl.h is not included in gretl_bundle.h, thus when
it looks for the definition of gretl_bundle it does not see it.
Is there any reason I couldn't move typedef struct gretl_bundle_ gretl_bundle back
to gretl_bundle.h, or move libgretl.h from gretl_bundle.c to gretl_bundle.h?
I am going to play around with it more later on and see what I can do
