Ian, Sorry, I missed to attach the patch 8) I prepared a patch for pex using pid_t instead of the type 'long' for system handles. This is necessary for _WIN64, because the long type isn't wide enougth to hold a pointer for this ABI The type pid_t is always defined by the configure in config.h if not defined by the header-set. Therefore it seems to be the best way to make this run. ChangeLog: 2007-08-03 Kai Tietz * pex-common.h: (pex_funcs): Retyped wait and exec_child to pid_t. * pex-djgpp.c: Likewise. * pex-msdos.c: Likewise. * pex-unix.c: Likewise. * pex-win32.c: Likewise.
