*
* Modified 12/91 by Dean Luick. Tim graciously donated this piece of code
* from his program ghostview, an X11 front end for ghostscript.
*
* + Make the cancel button optional.
* + Put an #ifdef SPECIAL_CMAP around code to fix a colormap bug.
* We don't need it here.
* + Add the function positionpopup() from another part of ghostview
* to this code.
*
* Modified 2/93, Various.
* + Added workaround for SYSV include problem.
* + Changed the default width response text widget to be as wide as the
* window itself. Suggestion from David E. Wexelblat, dwex@goblin.org.
*
* Modified 5/2015, anonymous.
* + Include nethack's lint.h to get nhStr() macro.
* + Use nhStr() on string literals (or macros from <X11/StringDefs.h>
* that hide string literals) to cast away implicit 'const' in order
* to suppress "warning: assignment discards qualifers from pointer
* target type" issued by 'gcc -Wwrite-strings' as used by nethack.
* (For this file, always the second parameter to XtSetArg().)
