- Remove DBUG calls from my_winfile.c where call and parameters
are already printed by mysys.
- Remove DBUG from my_get_osfhandle() and my_get_open_flags() to remove
DBUG noise.
- Updated convert-debug-for-diff to take into account windows.
- Changed some DBUG_RETURN(function()) to tmp=function(); DBUG_RETURN(tmp);
This is needed as Visual C++ prints for DBUG binaries a trace for
func_a()
{
DBUG_ENTER("func_a");
DBUG_RETURN(func_b())
}
as
>func_a
<func_a
>func_b
<func_b
instead of when using gcc:
>func_a
| >func_b
| <func_b
<func_a
