ECPG and typedef struct

Is it still necessary to define SQL TYPEs twice?

eg

typedef struct foo { ... } foo_t;

EXEC SQL TYPE foo_t IS struct foo { ... };

Is there some less maintenance-error-prone way to accomplish this? I
know about the -c option to ecpg, but this doesn't help if I need to
access the defined type from a .c file.

Ideally the C level typedef would be in a .h file somewhere and either
#include-ed or EXEC SQL INCLUDE-ed into .c or .pgc file

Thanks
