undefined struct 'pg_conn' on Windows7

Hello!
I install postgre from postgresql-9.3.5-3-windows-x64.exe file and try
use libpq.lib from it.
My system Windows7 ServicePack1 and I use VisualStudioExpress 12 for
write code.
I add path to <postgre_install_dir>\include and
<postgre_install_dir>\lib in project and include libpq-fe.h file.
Unfortunately when I try build project I get error "uses undefined
struct 'pg_conn'".
How can I solve this problem?
Thank you and excuse me for my bad english.

Can you show the C code?
Any chance that you use a variable of type "PGconn" when it should be "PGconn*" ?
