Hello again,
I've worked at this things. I'm not finished yet, but now I
know a couple of things better.

That is what I've done in the meantime.

I've simply omitted these two files, and I hope it works anyway.

That solution works fine, here my code therefore:
#ifdef __cplusplus
extern "C" {
# define delete __fake_delete
# define private __fake_private
# define new __fake_new
# define class __fake_class
// Add other defines for any conflicting C++ keyword
#endif
/*** include heartbeat headers here ***/
#ifdef __cplusplus
}
#endif

I worked out a solution for this thing, too. Just modify one line
in the definition from slist_iter:
(more precisely the line 196 in /include/crm/crm.h, version 2.1.2-3)
-- child = __crm_iter_head->data; \
++ child = (child_type *) __crm_iter_head->data; \
That works for my purposes.
Similar changes for the xml_child_iter macro in xml.h

Maybe I will report my final results with this subject,
or I will ask you many more questions ;)
