psqlodbc patches to unsiged short wchar definition on linux platform - Mailing list pgsql-odbc

Hello!

I successfully used the driver psqlodbc-08.01.0200 with postgres
database in UTF-8 encoding and with unsigned short wchar definition
after applying the following patches to the driver:

1) config.h

//#define SQL_WCHART_CONVERT

2) convert.h

My testing configuration:

server and client platform: Linux
psqlodbc configure: ./configure --with-unixodbc --enable-unicode
unixodbc: 2.2.11.

Please consider putting those changes to the driver. Without that driver
doesn't work correctly.
