That was a mistake on my end.  It will be added for the second version.

I will look into this.  I am using glibc for my project.

I'm not entirely sure about this.  By default, it does not install a 
configuration file.  There are several sample ones installed to 
/usr/share/mysql.  We could use my-small.cnf as it would probably be 
best suited to embedded systems.  The only thing I saw was all of the 
innodb stuff was commented out.  I'm using that for my project. Feedback 
from others would be welcome here.

No, I updated the version to the latest 10.1.17.  That will be part of 
my v2 patch.

I moved it to keep alphabetical order since I changed the name from 
mysql to mariadb in the Config.in file.
