Reading struct with structs

[Baillargeon, Sonny]

I am trying to read in a C struct file that contains sub-structs as part
as the data definition.  For example:
	int	a	/* 4 bytes */
	int_t	b	/* custom struct */
	blah_t	c	/* custom struct */
	bing_t	d	/* custom struct */

The custom structs are arbitrary.  The struct module only allows me to
have strict C datatypes.  How can I read in a struct recursively given I
have to feed the struct.unpack?

Thanks,
Sonny
