11 * Windows GUI.
12 *
13 * GUI support for Microsoft Windows. Win32 initially; maybe Win16 later
14 *
15 * George V. Reilly <george@reilly.org> wrote the original Win32 GUI.
16 * Robert Webb reworked it to use the existing GUI stuff and added menu,
17 * scrollbars, etc.
18 *
19 * Note: Clipboard stuff, for cutting and pasting text to other windows, is in
20 * os_win32.c. (It can also be done from the terminal version).
21 *
22 * TODO: Some of the function signatures ought to be updated for Win64;
23 * e.g., replace LONG with LONG_PTR, etc.
