throughout for subkey name buffer size. * fhandler_socket.cc (search_wsa_event_slot): Use MAX_PATH instead of CYG_MAX_PATH for mutext name buffer size. (fhandler_socket::init_events): Ditto. * fhandler_virtual.cc (fhandler_virtual::opendir): Check path length against PATH_MAX instead of against CYG_MAX_PATH. * registry.cc (get_registry_hive_path): Use PATH_MAX instead of CYG_MAX_PATH for registry value path buffer size. * shared.cc (open_shared): Use MAX_PATH instead of CYG_MAX_PATH for shared memory name buffer size. * thread.cc (semaphore::semaphore): Use MAX_PATH instead of CYG_MAX_PATH for semaphore name buffer size. * uinfo.cc (cygheap_user::env_userprofile): Use PATH_MAX instead of CYG_MAX_PATH for temporary path name buffer size. * winf.h (LINE_BUF_CHUNK): Define as MAX_PATH * 2. * include/sys/dirent.h: Include sys/limits.h. Define name buffer sizes using NAME_MAX.

bigger than this value, the stack position is suddenly moved up by 64K for

no apparent reason, which results in subsequent forks failing. Since Cygwin

processes get the full command line as argv array anyway, this only affects

the maximum command line length of Cygwin applications which nonsensically

have a WinMain instead of a main entry point or which use GetCommandLine. */
