Upgrading to cygwin 1.7.6 vs gcc 4.5

Upgrading to cygwin 1.7.6 vs gcc 4.5

[Ross Smith]

I've installed the experimental gcc 4.5 packages (because that's the 
version I'm using in all my other development environments, and it's 
nice not to have to target multiple compiler versions any more), but now 
that cygwin dll 1.7.6 is out, I can't seem to find a way to upgrade 
cygwin without also downgrading gcc. In the installer, if I select 
Current I get the new cygwin but the old gcc, while if I select 
Experimental, it keeps the new gcc but doesn't offer me the new cygwin.

At the moment I'm sticking with the old cygwin, because the gcc upgrade 
is more important to me than the cygwin upgrade. Is there some way I'm 
missing to select both, or do I just have to accept that I can't upgrade 
anything else until the official gcc 4.5 is ready?

Stay on the 'Curr' (not 'Exp'), click 'View' until you are on the
Pending page, then cycle on the string next to each gcc package until it
says Keep instead of the downgraded version number.

Yes, it's a known pain that setup.exe tries too hard to downgrade
experimental packages.  I still remember the pain of the couple of years
during cygwin 1.5 days where the only working emacs was marked
experimental, and I had to go through this exercise of manually
requesting that it not be downgraded every time I ran setup.exe for
anything else.  Patches welcome.

I'd recommend selecting the 'Exp' button actually. That ensures that
all dependencies of gcc, e.g. libgcc and libffi, are upgraded to 4.5
too. (It's yet another flaw of setup.exe that it doesn't automatically
upgrade dependencies of experimental versions accordingly.)

Of course this also selects experimental versions of a few other
packages, e.g. emacs, but if you don't want to help testing those, you
can downgrade them on the Pending page.

Scratch that. I hadn't realised that if you select 'Exp',
non-experimental packages no longer get updated, which of course is
exactly what the OP was saying. This is awful.

This should be fixed in the newly uploaded setup.exe 2.721.
