Yes, this is a known limintation. It's even listed in the TODO file. For
ECPG to be able to understand your variable it has to know the definition of
the struct. Since it is not listed in your declare section it cannot learn
the details and thus won't be able to parse the construct.

Please try:

exec sql begin declare section;
struct {
int id;
char value[40];
} *pmr;
exec sql end declare section;

This should work. But be sure to use the latest CVS version as there was a
small bug in this bug. I'm actually committing the fix right now.
