[ANNOUNCEMENT] New package: windows-default-manifest-6.3-1

[ANNOUNCEMENT] New package: windows-default-manifest-6.3-1

[Corinna Vinschen]

Hi folks,


I just uploaded windows-default-manifest-6.3-1.

This new package contains nothing but a default application
compatibility manifest, which gets linked in by GCC by default, and
which is supposed to claim compatibility with the latest Windows
versions available at the time.

Adding such a manifest got necessary due to a change in Windows 8.1.  On
earlier OS versions, applications without manifest were treated as
compatible with the current OS.  Starting with Windows 8.1, an
executable without manifest is treated as being compatible only with the
oldest supported OS version of the OS compatibility layer.

That means, all applications without manifest are running in a Window
Vista compatibility layer on Windows 8.1.  This affects all Cygwin
executables to date.  By adding the default manifest to newly built
packages, we're slowly getting to run our executables with full OS
compatibility.

This package is in the "Base" category, so it will be pulled in by
default.  The version number reflects the OS kernel version supported
by this manifest (6.3 == Windows 8.1).

For reference:

* http://msdn.microsoft.com/en-us/library/windows/desktop/hh848036%28v=vs.85%29.aspx

It would be too nice if this change would be consistent throughout
all APIs.  But no.  GetVersionEx returns "Windows 8" as version:

Live long and prosper,

Does this mean we should rebuilt all the application to
make W8.1 happy ?

Grrr ....

My reaction exactly, when I first read about this issue!

No, you don't have to rebuild your packages.  You can do that if you
like, but it's not pressing, so it's ok if the next packages will pick
this up.  Also, thanks to Microsoft we'll be behind every time a new
Windows version is released.  We can't just rebuild the entire distro
every time.

Did you read the comments in the 2nd link I sent with my announcement?
There are more unhappy devs...

I read. Very stupid broken behavior and also very dangerous for them
Forcing people to rebuild/restest application could push them to
move away.
Here iMac is gain a lot of share of new machine...

I saw also another stupid pseudo security claim 2 block
