Thank you very much for your test. I fixed this memory leak bug, and fixed .gitignore.
I also fixed some code style to fit coding conventions,
and splited my patch into 4 parts to improve readability:
* 001_declareStmt_preproc_v3.patch
* 002_declareStmt_ecpglib_v3.patch
* 003_declareStmt_doc_v3.patch
* 004_declareStmt_test_v3.patch
Here is a short summary:
[001_declareStmt_preproc_v3.patch]
This enables ecpg to pre-process "DECLARE prepared_name STATEMENT".
prepared_name is buffered to g_declared_list to check duplication of prepared_name.
After pre-processed, "DECLARE STATEMENT" is translated to ECPGdeclare().
And CUSRSOR STAETEMENT such as OPEN/FETCH/CLOSE cursor is translated into ECPGopen()/ECPGfetch()/ECPGclose().
These new function is defined at 002_declareStmt_ecpglib_v3.patch.
[002_declareStmt_ecpglib_v3.patch]
This patch mainly implements ECPGdeclare(), ECPGopen(), ECPGfetch(), ECPGclose().
ECPGdeclare() links the declared name and connection name.
Handling CURSOR things are originally done by ECPGdo().
But in order to handle connection linked to declared name,
the functions such as ECPGopen(), ECPGfetch()and ECPGclose() are introduced and these functions wraps ecpg_do().
[003_declareStmt_doc_v3.patch]
Docs. I wrote the DECLARE STATEMENT itself.
And added another example to ecpg-set-connection.
[004_declareStmt_test_v3.patch]
Regression test and answers.
I made them but I'm thinking these include too much test cases, don't they?
So I'm planning to make it smaller.

Ideriha Takeshi
