PATCH: Remove strdup use in libgui

[Mo DeJong <mdejong at cygnus dot com>]

Hi all.

Here is a little change I checked into src/tclhelp.c that gets
rid of the last use of strcpy in libgui. This should not change
the functionality of any code in Insight.

cheers

	* config.h.in: Regen.
	* configure: Regen.
	* configure.in: Don't check for strdup since it
	is no longer used in libgui.
	* src/tclhelp.c (help_initialize_command): Replace
	use of strdup with calls to malloc and strcpy.
