I compiled PostgreSQL 7.3.4 libpq for Win 32 using VC++ 7 compiler.
Compiler generates a libpq.lib file. Build a simple C program which opens and
closes a database connection.
When try to link object program and libpq library, following error occurs:

I don't know if additional postgre libraries are missing.
I appreciate some help.
Best Regards.
