Two patches included:
- the first one enables the use of bool variables in fields which might
become NULL.
  Up to now the lib told you that NULL is not a bool variable, even if
you provide a indicator.

- the second patch checks whether a value is null and issues an error if
no indicator is provided.

Sidenote: IIRC, the variable should be left alone if the value is NULL.
ECPGlib sets it's value to 0 on NULL. Is this a violation of the
standard?

See attached file. Now accepts "exec sql whenever sqlwarning".

remaining shift/reduce conflict. But the very same conflict is in gram.y, so
I don't dig into it very much now.

Anyway, I just saw that there were minor changes made to ecpg by others. Now
I like that but I would prefer if I was told about that. Otherwise my
version numbering and Changelog maintaining might break. Or simply change
these too. :-)

Also I had to add #include <errno.h> to  backend/libpq/pqcomprim.c to be
able to compile postgresql.

Patch is attached. Since my resubscription process is still not finished
yet, I still send them here.

yet. It's just a small patch to ecpg to keep it in sync with gram.y.
