56 // http://sourceforge.net/p/mingw-w64/bugs/395/

62 // default for MinGW targets in 13473c7 for jemalloc.

65 // after reading some code it at least *appears* that the initialization
66 // of mutexes is otherwise ok in jemalloc, so shouldn't cause problems

70 // locking, but requires passing an option due to a historical
71 // default with jemalloc.
