Sergey, I noticed these while building my recent bug fixes, but I wanted to fix them in a separate patch. Patch will follow very soon. Timour

Hi Timour,

When one compiles 5.3, it produces the following warnings which I believe fall into your turf. Could you please fix them:

item_subselect.cc: In member function ‘bool subselect_rowid_merge_engine::init(MY_BITMAP*, MY_BITMAP*)’: item_subselect.cc:4826: warning: ignoring return value of ‘int handler::ha_rnd_init(bool)’, declared with attribute warn_unused_result item_subselect.cc: In member function ‘virtual bool subselect_rowid_merge_engine::partial_match()’: item_subselect.cc:5007: warning: ignoring return value of ‘int handler::ha_rnd_init(bool)’, declared with attribute warn_unused_result item_subselect.cc: In member function ‘virtual bool subselect_table_scan_engine::partial_match()’: item_subselect.cc:5174: warning: ignoring return value of ‘int handler::ha_rnd_init(bool)’, declared with attribute warn_unused_result
