gtk/gdk/win32/gdkfont-win32.c
Tor Lillqvist f527b8909f Don't define HAVE_DIMM_H if MSC, as you have to get the Platform SDK to 
1999-11-04  Tor Lillqvist  <tml@iki.fi>

* config.h.win32: Don't define HAVE_DIMM_H if MSC, as you have to
get the Platform SDK to get <dimm.h>.

* gdk/win32/gdkevents.c: More event handling fixes and
simplification. Never generate motion events with is_hint true. We
used to do that on bogus grounds earlier. Windows sends
WM_MOUSEMOVE messages on button events even if the mouse hasn't
moved, ignore these.

* gdk/win32/gdkfont.c: Load all fonts as (pretended) fontsets.

* gdk/win32/gdkglobals.c
* gdk/win32/gdkprivate.h: Define a typedef for the pointer to
the TrackMouseEvent function, and use it.

* gdk/win32/gdkwindow.c: Terminate widechar string with a zero
char before calling WideCharToMultiByte in order to get a string
for the window title.

* gdk/win32/gdkdnd.c: Some more random hacking, ifdeffed out.

* gdk/win32/gdk.def: Remove obsolete functions.

* gdk/win32/makefile.{cygwin,msc}: Remove gdkcompat.{o,obj}. Add
/nodefaultlib and /defaultlib switches.

* gtk/gtkrc.c: s/gwin_getlocale/g_win32_getlocale/.
