Description:
Hi, I has some problems while trying to build a program written in C++ (Windows 2000, Microsoft Visual Studio 6.0 - in Linux I don't have this problem) that uses MySQL client library (I'm using CMake to build), I've solved the problem modifying the 'include/config-win.h' file, the problem was with the typedef to 'bool', a verification must be made to check if the build is in a C++ environment. Is the solution correct for you?

Follows the patch, the important part is only:

+#if !defined(bool) && !defined(bool_defined) && (!defined(HAVE_BOOL) || !defined(__cplusplus))
 #define bool BOOL
+#endif

I has cloned the verification from 'include/my_global.h'.

Thank you.

How to repeat:
On include 'include/config-win.h' through 'include/my_global.h' on a Windows application the bool type is redefined.

Thank you for the bug report. Could you please provide a small console
client application which presents the behavior reported?. I will test
with VS2003/2005 because VS 6.0 isn't more supported to compile client
and servers build. Thanks in advance.
