Windows C API Gives me compiler issues

[Daniel Brown]

Hello,

I am having issues updating to a newer version of the C API than what I am currently using.
I do not know exactly which version I am using now, except that I can compile it just fine and that it's copyrighted 2003.

I downloaded the 32-bit windows C API.
I am using it in a LabWindows CVI Project.

I included libmysql.lib and mysqlclient.lib in my project. I also included libmysql.dll.
I also included MySQL.h in my custom header file.

When I compile, I constantly get an error that it cannot find <sys/types.h> or <io.h> header files.
I believe this has to do with the MYSQL_ABI_CHECK not being defined.
My old MySQL.h does not have a MYSQL_ABI_CHECK, and thus is not an issue.

What is MYSQL_ABI_CHECK? How do I include/install it?

Can anyone suggest why I am having these issues? I have tried everything I can think of. Much appreciated.
