Maybe it's the initialization, that could be done in another way (e.g. a
separate unit if necessary):

<unit hdf5> 
unit hdf5;
...
initialization

	{ C has this in macros all over the place. Since it has to be done
	  once we do it here before anything else happens and are happy :) }
	H5open();
	
	{ Initialize standard type vars for copying }

	H5T_NATIVE_CHAR := H5T_NATIVE_SCHAR_g;
	H5T_NATIVE_SCHAR := H5T_NATIVE_SCHAR_g;
...
</unit hdf5>
