required.
* errno.cc: Use DWORD to hold Windows errors.
(geterrno_from_win_error): New function.
(seterrno_from_win_error): Use geterrno_from_win_error to convert supplied
windows error (suggested by Corinna Vinschen).
* path.cc (symlink_info): Add error element.
* path.cc (path_conv::check): Remove errno setting. Use new symlink_info errno
element to set path_conv error, where appropriate.
(symlink_info::check): Set error element rather than attempting to manipulate
errno. Add more checks for trailing / and /.. even though they are currently
useless. Avoid setting EINVAL.
* path.cc (normalize_posix_path): Correct check for trailing /.
* *.cc: put winsup.h before other headers (for __INSIDE_CYGWIN__);
use cur_environ() instead of just environ
* times.cc: remove import protections
* glob.c: add winsup.h
* localtime.c: ditto
* smallprint.c: ditto
* Makefile.in: don't __INSIDE_CYGWIN__ as it messes up profiling.
for second argument.
* path.h: Generalize SYMLINK_* constants to PC_*.
(path_conv): Create a new method. Fold third argument into second.
* dll_init.cc (dll_list::alloc): Try harder to find space to allocate dll
struct.
(dll_dllcrt0): Don't check sanity if we've already called dll_crt0.
* path.cc (path_conv::check): Don't check for a null or empty path unless
specifically told with a flag setting.
(check_null_empty_path): New function, adapted from macro.
* syscalls.cc (_rename): Use already-determined file attributes rather than
checking again.
* lib/cygwin/cygwin_attach.dll.c (cygwin_attach_dll): Use a static per_process
structure since this is apparently supposed to be zeroed.
* lib/cygwin_crt0.c (cygwin_crt0): Zero per_process structure sent to older
DLLs.
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.
(dll_crt0_1): Eliminate user_data initialization.
(dll_crt0): Set up impure_ptr_ptr for older executables.
(cygwin_dll_init): Eliminate user_data initializations.
(__api_fatal): Don't check for user_data initialization.

just a pointer.
(add): Ditto.
(initOneDll): Don't check for user_data initialization.
(DllList::recordDll): Store contents of per_process argument.
(DllList::detachDll): Pass address of per_process field.
(DllList::initAll): Ditto.
(DllList::doGlobalDestructorsOfDlls): Ditto.
(DllListIterator::operator *): Ditto.
(dll_dllcrt0): Default to __cygwin_user_data if arg is NULL.
* include/sys/cygwin.h: Reorganize per_process to eliminate obsolete fields and
accomodate new way of initializing.
* lib/_cygwin_crt0_common: Initialize _impure_ptr from
