Patch name: patch.win32-keyevents
Author: Volker Ruppert
Date: Sun Feb 16 12:55:00 CET 2003
Status: applied to main code

Detailed description:
  This patch fixes the key handling of the win32 gui. Now the function
  DEV_kbd_gen_scancode() is called instead of DEV_kbd_put_scancode(). This
  change enables the support for different scancode sets. The win32 scancodes
  are now converted to bx_key values.

Patch was created with:
  diff -u
Apply patch to what version:
  cvs checked out on DATE
Instructions:
  To patch, go to main bochs directory.
  Type "patch -p0 < THIS_PATCH_FILE".
