Can you tell me exactly the flag and where to put it to build a version of
TDS with the enable-developing flag set?

THANKS.

I added your program (modified) to ODBC unittests.
First time I tried it it succeed (I tested also returned values).
After a while I realize that I was using --enable-developing configure
flag.
This flag mainly enable a new version of SQLExecute that improve
performance but have still some problem. I fixed some of them but others
remain:
- Sybase isn't unable to use dynamic statement using text/image fields
(you have to build language text or use TDS_LANGUAGE with parameters,
still not implemented)
- SQLPutData do not work (SQLExecute return SQL_ERROR instead of
SQL_NEED_DATA)
- TDS 4.2 is not supported (well, this is not a big problem, I hope
nobody use this version..)

There are already unittests for both cases (bynary_test and putdata) so
I hope to fix them ASAP.
