Looks like 37871b73 by Giuseppe Bilotta does not work very well on Windows. Instead of a former tcl/tk icon, the window has a black square as an icon.

This patch is a copy-paste from Git Gui, which uses a separate .ico file when it runs on Windows platforms. --- The patch is in line with what Giuseppe Bilotta proposed in [PATCH] gitk: try to set program icon on 2008-11-15 23:45:45 GMT Unfortunately, I could not find any particular reason why that patch was not applied, but without it, Gitk on Windows does not look as nice as it could.

The changes in the Makefile were only sanity-checked, not tested in the full-fledged build or install.

CC to msysGit list is because the changes are actually made and tested on top of git version 1.6.4.msysgit.0.597.gcd48

these bits look unrelated and should probably be in a separate submission.

The only reason this code is here: Git Gui has it in the same section. Given my total lack of Tcl/Tk skills and deep understanding, I hoped to fix some other Windows-specific annoyances "by accident".

If Tcl/Tk gurus, for example, Paul Mackerras, say they're wrong, I'll gladly remove them. If the only objection is the inclusion into the same patch, I can do that too.

Thanks for your time!

I've been using versions of gitk on Windows with that patch since it
was applied in March and it has been fine. On Windows XP and Windows
7. So there is more to this than you are telling. Are you using
windows via remote desktop? There was a patch committed to Tk a while
ago about the program icon displaying as a black square over remote
desktop. If so, this requires an updated Tk and not a patch to gitk -
tk 8.5.8 should be ok if this is the problem.

You're absolutely right about *unintentional* withdrawal of facts in my original message, but no, I'm not using Remote Desktop. However, my XP SP3 has 16-bit colors and apparently 8.5.7 can't display those photos correctly in this case either. Most probable reason why the issue was first discovered in Remote Desktop is because most of RDP sessions are limited to 16-bit colors.

Unfortunately, the situation is improved with 8.5.8, but definitely not resolved (tested on msysGit devel branch). The sequence image create photo && wm iconphoto on 16-bit displays in XP SP3 renders the background black, not transparent. The fact that I'm using Classic color schema may play some role too. I'd speculate that 8.5.8 on Windows 7 (admittedly, it's much harder to switch to 16-bit colors there) may have exactly the same issue, given that 8.5.7 has exactly the same symptoms.
Is there a way to replace the "simplistic"
if {$::tcl_platform(platform) eq {windows}}
with something more elaborate that takes into account 16-bit colors?

No - it will be the use of 16bit color. Classic gets used a lot, 16 bit colour - well, you might be the only one now so such a system has limited testing.

That is better done using 'if {[tk windowingsystem] eq "win32"} {...}'. The windowingsystem command is preferred over platform because they are not always equivalent (for instance, MacOSX may use either x11 or aqua). To test the colour-depth there is [winfo depth .] which returns 16 when using the 16bit color on XP and 32 on Win7 with full color.
