Error compiling a simple C program

OS: Windows XP service pack 3
MySQL Server v 5.5
C Compiler MINGW - Minimalist GNU for windows

I am trying to write a simple C program to access a mysql database as follows:
#include <my_global.h>
#include <mysql.h>

int main(int argc, char **argv)
{
printf("MySQL client version: %s\n", mysql_get_client_info());
}
I have copied the include files that came with mysql server 5.5 to the include directory on the MINGW compiler directory structure.

When I try to compile I get the following error:

In file included from c:\mingw\bin\../lib/gcc/mingw32/4.7.2/../../../../include/io.h:20:0,

compilation terminated.

Am I using the correct include files? I have also tried the include files from Connector C 6.0.2 but get similar errors?

What am I doing wrong?
