+Problem has been reported upstream and closed with WONTFIX:
+http://bugs.musicpd.org/view.php?id=4387
+http://bugs.musicpd.org/view.php?id=4110
+
+however...
+
+POSIX does not permit using PTHREAD_COND_INITIALIZER except for static
+initialization, and certainly does not permit using it as a value
+
+POSIX does not specify the type of the object (it's opaque) so if
+there are any types for which their code would be invalid C++, then their
+code is invalid
+
+Volatile in the type is necessary. without that, LTO can break the code.
