abhi5466 · dahlerlend · commit 7a991ac1db6e · 2017-09-10T12:40:17.000+02:00
Post push fix:

Compilation with clang fails with error 'class member cannot be redeclared'
for class Attachable_trx_rw.

Definition of class Attachable_trx_rw is moved inside class THD.
Remove forward declaration of class Attachable_trx_rw and declaration
of class Attachable_trx_rw_i_s from class THD.
