This was always a bit weird. A 'cd /proc' never actually cd'ed to
something, so a native Win32 process ended up in the previous cwd.
We discussed this on cygwin-developers.
As for long pathnames, they weren't accessible before at all.
And it's really not my fault that Win32 processes are not able to deal
with CWDs > 259 characters. The original Win32 layer programmers IMHO
seriously screwed up when they decided to store the CWD in a 260 WCHARs
wide static array in the PEB instead of dynamically allocating the path.
Having said that, they also screwed us all with the strange distinction
between normal and long pathnames in the Win32 API.

This turns out to be sort of a nightmare, but I'm still glad I did it.
We now have full wide char support and setting $LANG/etc does really
something useful. I can't imagine how painful it would have been to
drag this change along in small steps.
Apart from the bugs I introduced with this change, what's missing is
real support for file-based locale data in /usr/share/locale and
support for the other LC_ categories (LC_TIME, LC_MONETARY, etc).
But that's something which can be improved over time.

That change only affects how mount points are stored. The day to day
usage is the same, basically.

Only applications which haven't been rebuilt for more than 10 years.

That's still a sore point. Dave, is there any chance we can switch
to gcc-4 as standard compiler for Cygwin 1.7 within the next 4 weeks?

Yeah, we should stop right here. The biggest problem left is the
native language support, apparently. I'm still hoping to get
1.7.1 out of the door end of this month, though.
What's left, AFAICS is
- The usual bugfixing.
- Creating the final version of setup-1.7.exe and replace
cygwin.com/setup.exe with it.
- Move the old documentation somehwere else, move the new docs to
the old place. (And don't forget to remove the "1.7" subdir from
the URLs in the docs).
- Splitting off the union FS for release-2.
- New versions of GCC and binutils would be nice. I'd especially
appreciate if GCC would start to create executables with the TS-aware
flag by default so that the distro is sort of self-healing in terms of
running on Terminal Servers.
Am I missing something else?
