This seems to be an upstream bug. The variable my_thread_end_wait_time is not defined in any .h file included by the file driver/dll.c nor anywhere else in that file. It is only defined as a global static variable in another file(mysql_sys/my_thr_init.c) aka not visible outside that file. It may be that to fix it, with an emphasis on the may be, they only need to make it a declaration and not just an assignment in dll.c, that means add `static uint` before "my_thread_end_wait_time = 0;" at line 114. I did not read what's going on in that file, to be sure, just noticed it is not a valid C program. It may also be this is code not removed that should have been removed, since my_thread_end_wait_time does not seem to be used at all in that file. Take this to upstream, they should be able to know what to do to fix it, once there is a patch, make emerge use it, or wait for it to be added to the portage tree.
