I tried to add as native functions. (Re: Porting "distance_sphere()" and "distance_spheroid()" to MySQL.)

[Koji Okumura]

I tried to add these functions (distance_sphere and distance_spheroid) as native functions for MySQL.

Please refer our site: "I tried to add GIS functions (distance_sphere and distance_spheroid) as native functions for MySQL."

P.S.
I think MySQL 5.1 Japanese (but not translated (T_T) ) document about adding native function , http://dev.mysql.com/doc/refman/5.1/ja/adding-native-function.html , is incorrect.
