"#error <my_config.h>" and third-party libraries

Details

    Description

      The safety check in my_config.h ensures that this file is always included before system headers.

      But when my_config.h is installed, this breaks compilation of various third-party projects. In particular, mysql-python doesn't compile anymore.

      While technically forcing my_config.h first is correct and mysql-python doesn't break by a sheer luck and, we still cannot force all third-party projects to include files correctly.

      This check has to be relaxed.

            Thanks. We got it to install by commenting out these lines in /usr/include/mysql/my_config.h:654

            #ifdef __GLIBC__
            		 
            #error <my_config.h> MUST be included first!
            		 
            #endif

            The workaround is to downgrade to 5.5.39, install MySQL-python and upgrade back to 5.5.40 (or newer).

            Hey, this seems to be a problem when installing MySQL-Python on Debian 7. Is there a plan to fix it? Cheers.

            Yes, it was merged into 10.0 after 10.014 release. So it's important to fix it before 10.10.15
