We have the following:

    $ fgrep 127 /usr/include/w32api/winerror.h | head -1
    #define ERROR_PROC_NOT_FOUND 127L

This error usually means the extension module did not export the init
function.  What do you get when you try the following?

    $ objdump -p _mysql.dll | fgrep init

For example:

    $ objdump -p zlib.dll | fgrep init
            [   0] initzlib

If the init function is not being exported, then change the source from:

    void
    init_mysql(void)
    {
        ...
    }

to:

    DL_EXPORT(void) /* for Python 2.2.2, use PyMODINIT_FUNC for Python 2.3+ */
    init_mysql(void)
    {
        ...
    }

See the following mailing list thread:
