Path Name: /hp-ux_patches/s700_800/10.X/PHCO_21018

Symptoms:
	PHCO_21018:
	1> While compiling <curses.h> with HP ANSI C++
	   compiler, it reports an error at 'bool'.
	2> The A_ATTRIBUTES macro in curses.h does not
	   have brackets.

	PHCO_16961:
	1> initscr() dumps core when TERM environment variable
	   is too long.
	2> Curses attribute functions do not work properly with
	   libxcurses.1

	PHCO_14654:
	The delwin(3X) coredumps in some cases.

	PHCO_11342:
	The X/Open curses API getch() waits indefinitely for
	input to complete a keypad sequence.

	PHCO_11036:
	Various XCurses APIs were fixed during 10.30 and
	the same had to be backported to 10.20.

	PHCO_9295:
	1.  In 10.20, high-lighted fields cannot be reverted
	    to normal in an application which links with -lcurses.
	2.  Application uses select() systems call  core dumps.

Defect Description:
	PHCO_21018:
	1> The type declaration for 'bool' in curses header file
	   creates a conflict with the keyword 'bool' in ANSI C++.
	   This is because 'bool' is a reserved word for ANSI C++.

	Resolution:
	   Changing the type definition of 'bool' in preprocessor
	   macro to avoid conflict with ANSI C++ solves the problem.

	2> The missing brackets around the macro A_ATTRIBUTES
	   can cause an operator precedence problem in some
	   expressions which use this macro.

	Resolution:
	   Adding the missing brackets to the macro solves the
	   problem.

	PHCO_16961:
	1> initscr() dumps core when the TERM environment variable
	   is too long. This is due to a buffer overflow in the
	   routine.

	2> X/Open curses do not take care of the 'sgr' entry of the
	   terminfo database, if the ceol_standout_glitch and the
	   magic_cookie_glitch are set in the database. This results
	   in display attributes not being properly set on terminals
	   like hpterm.

	PHCO_14654:
	The call to delwin() coredumps in some remote cases.
	This is basically because of a buffer overflow in the
	library.

	PHCO_11342:
	When keypad is enabled, the X/Open curses API getch()
	should wait for some time after <ESC> key is pressed for
	the next key to be pressed and return that sequence. If
	no key is pressed for some time the API should return
	<ESC> alone. Currently getch() waits indefinitely for
	the next key to be pressed when <ESC> is pressed.

	PHCO_11036:
	The 10.30 fixes to various XCurses APIs have been
	backported to 10.20.

	PHCO_9295:
	1.  10.20 X/Open curses: high-lighted fields cannot
	    be reverted to normal
	2.  10.10 enhanced X/Open curses core dumps due
	    to using wrong select call.
