[Dev-C++] Problems compiling a io_base.H

[Maya <Esc...@ne...>]

I am having some problems compiling a class that compiles under MinGW 
IDE. Here is the error I get, can anyone help?

2148 C:\DEV-CPP\include\winuser.h
previous declaration of `typedef struct

I am not including 'winuser.h'; DEV-C++ does it automatically, but I 
don't want to include that file. What can I do?

Thanks in advance!
