Subject: Make mysqlnd default over libmysql in 5.4
From: johannes.schlueter@oracle.com (Johannes =?ISO-8859-1?Q?Schl=FCter?=)

Hi,

when building PHP using
  (I) ./configure --with-mysql --with-mysqli --with-pdo-mysql
you currently get a build using the system default libmysql, usually
in /us or
such. Alternatively PHP can be built using
 (II) ./configure --with-mysqli=3Dmysqlnd [...]
to build the MySQL extensions using the mysqlnd library.

I would like to change mysqlnd's config9.m4 file to build PHP using
mysqlnd when being called in form (I). Users would still be able to
enforce libmysql by passing a path, like /usr.

There are two main reasons I see for this:
  a) Different libmysql versions have slightly different behavior,
     which shows in our tests. We can't have both, a good test coverage
     and cover all these differences. By using mysqlnd we have a clear
     behavior every PHP developer can rely on.
  b) We provide different extensions (pecl/mysqlnd_*) which
     improve/extend mysqlnd functionality. By having mysqlnd as default
     these are better usable by users.

Opinions?
