  75. **              are moved the shadow area will loose sync with

  96. **              (various)                               (V6.02)        
  97. **
  98. **  The following changes were incorporated in the 01/07/91 release:
  99. **
  100. **  12.26.90 -  wn_hlinit was allocating more memory than was needed.
  101. **              (wn_help.c)                             (V6.01)
  102. **
  103. **              TopSpeed "C" support added.

  105. **
  106. **              wn_gulong was short 1 byte on the mask it passes 
  107. **              to wn_input.c.  Thanks to the TopSpeed Compiler for
  108. **              finding this.
  109. **
  110. **              Moved v_getchm() to "wn_mouse.c" to eliminate including
  111. **              ANY mouse code from applications that do not call
  112. **              any of the mouse functions.  v_getchm() was previously

  115. **              Microsoft 6.00A certification.

  117. **  12.14.90 -  wn_close was not setting wn->shadow to FALSE when
  118. **              closing shadowed windows.  This was causing wn_activate
  119. **              to do potentially foolish things.       (V6.00)        
  120. **
  121. **  (11.01.90)  ** [Limited distribution release]
  122. **

  132. **
  133. **  07.18.90 -  Turbo C++ Support.  Created TCVLIB.ASM to get around
  134. **              Borland's oversight with regard to "CONST".

  138. **
  139. **  06.16.90 -  Cosmetic and misc changes: (BOSSDEMO.C,
  140. **              MAKELIB.BAT (LC6), include memory model directives
  141. **              for Lattice 6.XX batch files).

  143. **
  144. **              QuickC 2.5 Support.                            
  145. **

  147. **              NULL as an int.
  148. **              (windows.h)                                    
  149. **
  150. **  04.04.90 -  wn_help was taught to use wn_putsa to enforce user
  151. **              specified help screen attributes.  Tip of the hat
  152. **              to Chris Madsen.
  153. **              (wn_help.c)                             (V5.16)
  154. **
  155. **  03.23.90 -  Added "wns_escape". This is set to TRUE by wn_input
  156. **              whenever ESCAPE has terimated the input.  ESCAPE
  157. **              now terminates input for all input field types.
  158. **              (wn_gbool, wn_gdate, wn_double, wn_gfloat, wn_gphone)
  159. **              (wn_gtime, wn_guint, wn_gulong, wn_gint)
  160. **              Thanks Dexter!!                         (V5.15)
  161. **
  162. **  03.12.90 -  Due to popular request, wn_open now range checks
  163. **              the window parameters to make sure that the window
  164. **              will actually fit on the screen.  NULL is returned
  165. **              if not.  This will prevent some cockpit "bad handle"
  166. **              error exits.
  167. **              (wn_open.c)                             (V5.14)
  168. **
  169. **  03.08.90 -  Added wn_hlinit, wn_help, wn_popup, and wn_qpopup.
  170. **              These functions are close clones to the old sample
  171. **              code provided in help.c and popup.c.  HELP.C and
  172. **              POPUP.C will no longer be distributed.
  173. **              (wn_help.c, wn_popup.c, windows.h)
  174. **              (genindex.c)                            (V5.13)
  175. **
  176. **  03.07.90 -  Placed all "externals" in "windows.ext".  This is
  177. **              being done to ease the burden of making changes
  178. **              to both global and external data.  This will also
  179. **              keep all the constants in one p
