I think that for that kind of problem it could be a good idea to have a new
call in m_pd.h in which an external states to pd what its interpretation of
m_pd.h's structs is, so that pd can detect problems. e.g. m_pd.h could
contain a statement-like macro and a function decl:
#define pd_begin_setup() pd_make_sure(sizeof(t_text))
EXTERN pd_make_sure(size_t sizeof_text);
Actually, we don't need pd to check it for us, and we don't even need to
call a function to get the size of a class. E.g.
#include <stdio.h>
#include "m_pd.h"
#include "m_imp.h"
extern t_class *text_class;
void sanity_setup (void) {
post("t_text is %d bytes according to pd", text_class->c_size);
post("t_text is %d bytes according to me", sizeof(t_text));
}
So if text_class->c_size != sizeof(t_text) then the externals compiled
with the same options as this external will not be compatible with the pd
that loaded -lib sanity.
