Reading win32/win32.c waitpid implementation, maybe waitpid(-1, ...) on that platform will never conflict with mjit use of waitpid. In any case, I've added WAITPID_USE_SIGCHLD macro to vm_core.h so it can be easy for Linux/BSD users to test (hopefully!) win32-compatible code. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63855 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
