here an fix to make this work on win32 and also solve a potential issue of type:
(subsurface.bin:19441): Gtk-CRITICAL **: IA__gtk_entry_set_text:
assertion `GTK_IS_ENTRY (entry)' failed

my commit message is explicit on the reasons:
------------------------
When called from the "dive edit" dialog the, map windows seems
inactive on Windows. It cannot accept focus and is also behind all
other application windows.

There are a couple of important new calls in gps.c:show_map():
gtk_window_set_transient_for(GTK_WINDOW(*window), GTK_WINDOW(main_window));
(^ docs say gtk "may" call this one for us, on what condition - not specified)
gtk_window_set_modal(GTK_WINDOW(*window), TRUE);
(^ broken on ubuntu 12.04, but needed on Win32))

Making the window transient for the main window and also modal for
the entire application's window stack (or at least try).

Older versions of gtk+2 and also in the most recently tested
libgtk2.0-0 2.24.10-0ubuntu6, seem not to recognize the significance
of gtk_window_set_modal() and the call does not work as expected.
This forces us to check if the dialog from which the call originated
exists, since its possible to close it _while_ the map widget is active.

More specifically, we check in info.c if the location_update.entry pointer
was set to NULL before performing actions with in the update_gps_entry()
callback.
------------------------

also removed the gtk_window_present() call as it seemed redundant post
these changes (?).

Subject: [PATCH] Fix a "stacking" issue with the map-window on Windows

When called from the "dive edit" dialog the, map windows seems
inactive on Windows. It cannot accept focus and is also behind all
other application windows.

There are a couple of important new calls in gps.c:show_map():
gtk_window_set_transient_for(GTK_WINDOW(*window), GTK_WINDOW(main_window));
(^ docs say gtk "may" call this one for us, on what condition - not specified)
gtk_window_set_modal(GTK_WINDOW(*window), TRUE);

exists, since its possible to close it _while_ the map widget is active.

332d372b80 Pick GPS coordinates of dive location via map widget
I have some concerns about the way this is implemented - especially the
use of gtk_grab_add to make the map widget work has me worried. But it
seems to work and survived some test cases that I threw at it.

The GtkButton with the Pixmap looks a little off on my screen, but this
way it was easy to implement. Feel free to come up with a better design.

41027c2843 Make subsurface compile with -DGSEAL_ENABLE
This forces us to use the proper gtk accessor functions.  It may not be
worth it if people actually do the Qt conversion, but if we want to try
gtk3 at some point, this might help.

This all came about because I was trying to explain on G+ what an
immense pain this all was to even figure out, if you don't actually know
gtk at all.  Google and the gtk migration guide are almost useless, and
the gtk2 documentation itself actually uses the fields directly without
any accessor functions in several places.

075aba8f7d Fix the zooming bug in the map window
There are more events than scroll_up and scroll_down - and because of this
we could end up with target_lat and target_lon being uninitialized.

ae64abfbca Modify map zoom to keep the point under the mouse cursor constant
The idea is that while zooming the map the point under the mouse would
stay as close to constant as possible (given that we use integer
coordinates).

This version uses some algebra to figure out the correct new parameters
for the mercator projection used in osm-gps-map.

Occasionally (and we haven't figured out what triggers it) zooming out
suddenly resets your position to 0,0.

[Dirk Hohndel: switched this to using the correct interface to get the
               object properties and did some serious whitespace cleanup]

e618a245b9 Use proper helper functions for dive location and for_each_dive
This makes the code use the "dive_has_location()" function rather than
check the longitude and latitude directly.

It also uses "for_each_dive()" rather than open-coding it.

97ce7a3763 Fix map scrolling
The osm-gps-map default is to scroll-and-recenter around the mouse position.
That is BAT SHIT CRAZY. So this implements our own scroll handling instead.

980ba9cb50 Reuse map windows
Instead of opening a new window / new map for every dive site we now have only
two windows / maps. One for the overview of all the dive sites, the other one
that is used to show the map for a specific dive site.

This also switches the position preference from CENTER to MOUSE - this way it's
less likely that the two map windows will be drawn exactly on top of each
other.

e9953fa5e6 Show single dives in map.
This adds a "Show in map" entry in the dive list context menu.  It will
zoom to the dive location if it exists, otherwise the full map will be
displayed.

I've also switched map tiles from OpenStreetMap to Google Maps just to
show off that we can.

2330f9b379 Use the legacy GDK keyboard definitions in gps.c
display-gtk.h has a check if gdkkeysyms-compat.h or gdkkeysyms.h
has to be used. In gps.c, from such as "GDK_Up" has to be used,
so that this file compiles on older GTK.

8ff350387d Work on a dive localisation tool using GPS coordinates
For each dive recorded, place their GPS coordinates onto a map using the
OSM-GPS-MAP library.

This map is accessible via the "log" menu or the shortcut ctrl+M (M as map).

We check for the GPS coordinates "0, 0" which are the default when we do not
have real GPS coordinates set.

[Dirk Hohndel: fixed int/float math confusion, fixed some whitespace and
               coding style issues, cleaned up some comments, added a
	       missing cast to prevent a compiler warning]
