Subject RE: [patch] Removal of Windows build requirement on unicows.dll - issue 88652
Date Thu, 29 Sep 2011 00:55:11 GMT
The only reason for testing the installer on Win32 platforms older than Windows 2000 is to
find out how they fail.  If they don't fail that is interesting too, but I understand it is
not part of any agreed support.  If they fail, they won't be fixed.

I guess Oliver is our source for fresh Windows builds to try testing.

Funny, I just assumed you were a developer.  That's probably because I am a long way from
having been a professional developer.  Umm, well, 3-4 years but there are giant gaps between
developer gigs (e.g., 15 years before, then 10 years before that, etc.)

 This would help me set up a routine for doing that kind of QA in the future. (For different
internationalization variations, I can't do that alone and there needs to be help from the
NL community.)

I'm not a developer nor have I tried to build OOo from source for 
myself. (yes, I know, shame on me. ;-( ) However, I can offer some help 
to get some basic tests done for Win2000. A running version in a VM 
should be enough.

things too.

I remember that some code parts were deleted for supporting Win95/98/ME 
in the past. So, I'm pretty sure that it will not work on these Win 

So, please correct me if I'm wrong but when we speak about "supporting 
older versions than WinXP" it's only Win2000 we speak about.
