No, you cannot use bitpacked records for C header translations.  
Bitpacked records are not guaranteed to have the same layout as in C  
(or even in different versions of FPC). If it works, you are lucky,  
and it will probably fail on some other platform or in another FPC  
version one day.

The internal format of bitpacked records is opaque, and it is  
impossible to express the alignment requirements of C bitpacked  
structs or their internal fields with them.
