Hmm. Are you sure you've got a compatible version of MySQL? These
errors has nothing to do with the build system per se. Rather, it's
errors/warnings that spring up if the functions mysql_drop_db() and
mysql_create_db() have not been declared in your code, either via a
header inclussion or an explicit declaration.
Check if your MySQL headers really does contain the declarations with:
grep "mysql_drop_db\|mysql_create_db" /usr/local/mysql/include/mysql.h
Some thing like
int STDCALL mysql_create_db(MYSQL *mysql, const char *DB);
int STDCALL mysql_drop_db(MYSQL *mysql, const char *DB);
should show up.

The build system works :-) The reason it still fails, is that it has
nothing to do with the build system.

Something may be screwy in your MySQL installation. Try installing
the regular RPMs, DEBs, whatever, for your system, if you have that
possiblity. Otherwise, menace your BOFH [1] until s/he finally
succumbs - usually works for me :-)
