* exec.cc (_execve): add missing const to args to match def	of execve in newlib which this calls.	(sexecve): add missing const to def	(sexeclpe): don't need to cast argv in sexecvpe call	(sexecvpe): add missing const to def	* winsup.h: correct _execve proto, add protos for login/logout	* syscalls.h: correct sexecve, sexecvpe protos	* include/Windows32/Base.h: NULL should be defined differently	for C++	* init.cc: respacingTue Sep 23 17:05:50 1997  Geoffrey Noer  <noer@cygnus.com>	patch from sos@prospect.com.ru (Sergey Okhapkin):	* dcrt0.cc (dll_crt0_1): don't use alloca for allocating storage	for environment blocks because setenv() uses realloc!Tue Sep 23 17:05:50 1997  Geoffrey Noer  <noer@cygnus.com>	patch from cgf@bbc.com (Chris Faylor):	* Makefile.in (LD_STUFF): Add datestamp.o after DLL_OFILES.        (datestamp.o): New target.  datestamp.c is generated whenever .o        files change.  It creates a file containing a "date stamp"        which is used by the function "cygname" to create named	shared memory, events, mutexes, and semaphores used by	cygwin.dll.  The unique datestamp allows multiple loading of	different cygwin.dll's even when they have incompatible use	of shared memory areas.	* init.cc (dll_entry): Create the name string used by cygname        from the name of the invoking .dll + the datestamp of the        .dll from the auto-generated datestamp.c        * misc.cc (cygname): New function.  Creates a standard Cygnus        shared resource name given a prefix, a name (e.g., pinfo_mutex),        and a numeric suffix (e.g., a pid).  Replaces custom code in        several files.  Uses cygwin_dlldate from datestamp.c to construct        names that are unique for a given cygwin load.        * shared.cc (open_shared_file_map): Use standard cygname function        to create names for sharable objects.  Use static handle 'h'        so that it can be closed later by shared_terminate.        (shared_terminate): Guard against calling CloseHandle with a        NULL handle.        (create_shared_fd_mapping_name): Use cygname function to generate        the name for the "fd_map".Tue Sep 16 23:34:36 1997  Geoffrey Noer  <noer@cygnus.com>	patch from sos@prospect.com.ru (Sergey Okhapkin):	* fcntl.cc (_fcntl): correct errno value (EBADF instead of	EBADFD).Tue Sep 16 17:22:28 1997  Geoffrey Noer  <noer@cygnus.com>	patch from sos@prospect.com.ru (Sergey Okhapkin):	* include/Windows32/Defines.h: add missing defines needed	for NTEA usage.	* ntea.cc: remove them from here	* syscalls.cc (_link): call CreateFile with FILE_WRITE_ATTRIBUTES	flag instead of GENERIC_WRITETue Sep 16 17:22:28 1997  Geoffrey Noer  <noer@cygnus.com>	patch from cgf@bbc.com (Chris Faylor):	* pinfo.cc (pinfo_init): Fix a NULL pointer dereference when PID	environment variable contains garbage.Thu Sep 11 16:51:40 1997  Geoffrey Noer  <noer@cygnus.com>	* syscalls.cc (ftruncate): read file pointer location at	beginning of function and restore it at the endThu Sep 11 15:35:10 1997  Ian Lance Taylor  <ian@cygnus.com>        * path.cc (backslashify): Don't turn a single trailing slash into        a double trailing slash.Wed Sep 10 11:40:55 1997  Ian Lance Taylor  <ian@cygnus.com>        * include/Windows32/Structures.h: Add PACKED to PRINTDLG.        * include/Windows32/Functions.h: Add STDCALL to a few function        declarations.Tue Sep  9 02:12:18 1997  Geoffrey Noer  <noer@cygnus.com>	patch from sos@prospect.com.ru (Sergey Okhapkin):	* syscalls.cc (_link): Implement hard links under NT with NTFS	using the backup API.  Default to copying the file (what we did	before).Mon Sep  8 20:19:09 1997  Geoffrey Noer  <noer@cygnus.com>	Merge in the following changes:        Thu Aug 21 13:30:12 1997  Ian Lance Taylor  <ian@cygnus.com>        * assert.cc: New file.        * Makefile.in (DLL_OFILES): Add assert.o.

(spawn_guts): Sort the environment before passing it to	CreateProcess.        * exceptions.cc (exit_already): New file static variable.        (__cygwin_exception_handler): If exit_already is set, just        return.  If we get an exception we don't recognize, let the next        exception handler handle it.  Just ignore the INVALID_HANDLE        exception.        (really_exit): Remove file static exit_already variable; use the        global one.        (events_terminate): Set exit_already.        * include/Windows32/Defines.h (EXCEPTION_INVALID_HANDLE): Define.        (STATUS_INVALID_HANDLE): Define.        * include/Windows32/Functions.h: Declare some shell functions.Mon Sep  8 17:40:46 1997  Geoffrey Noer  <noer@cygnus.com>	patch from sos@prospect.com.ru (Sergey Okhapkin):		* dcrt0.cc (_exit): Kill the foreground process group on session	leader exit only if job control is in progress.	* exceptions.cc (ctrl_c_handler): protect the code with critical	section.

Add definitions that	will eventually be used to build a cygwindebug.dll used by gdb	so gdb can debug a buggy cygwin.dll.  Change some variable names	to have underscores in them (DLL_NAME, LIB_NAME, DEF_FILE, etc.).	Comment out text.exe build rule.
