Description: Use standard mutex and condition variable classes
|
|
Use std::recursive_mutex and std::condition_variable instead of custom classes
|
|
based on pthread.
|
|
.
|
|
Fixes FTBFS with recent GCC versions which defines the "mutex" class which
|
|
conflicts with seq24's version of "mutex".
