* hinfo.cc (hinfo::linearize_fd_array): Make max_used_fd an int so that we can
detect when there are no fds to pass. * dcrt0.cc (host_dependent_constants::init): Revert Sat Mar 18 01:32:04 2000 change. (dll_crt0_1): Set "cygwin_finished_initializing" flag. (dll_crt0): Don't perform memcpy if uptr is already set to internal structure. (_dll_crt0): Remember location of programs envptr. * dll_init.h (per_module, dll, dll_list): Revamp. * dll_init.cc: Revamp. Use new classes. * fork.cc (fork): Use new revamped dll, dll_list, and per_module stuff. * environ.cc: Use __cygwin_environ throughout rather than the user_data->envptr. * exec.cc: Ditto. * spawn.cc: Ditto. * winsup.h: Declare update_envptrs, cygwin_finished_initializing. * lib/_cygwin_crt0_common.cc (_cygwin_crt0_common): Revert previous change. * lib/cygwin_attach_dll.cc (cygwin_attach_dll): Always pass in own per_process structure or we end up overwriting information from the main program.
