Updated: cygwin-1.5.25-1

           ==== CYGWIN THANKSGIVING EDITION ====

I've made the new version of the Cygwin DLL, 1.5.25-1, and
associated
utilities available for testing.  Version 1.5.24-2 remains
the current
version for now.

This is a bug fix release.  Important changes since
1.5.24-2:

- Always add LOCAL and INTERACTIVE groups to user tokens to
fix some
  permission problems on Windows 2003 Server and later.

- Set preferred IO blocksize to 64K for performance
reasons.

- Add missing baudrates for serial IO up to 3.000.000 baud.

- Fix various race conditions in process exit, in dll
initialization,
  when starting native Win32 processes, and in signal
handling.

- Fix a couple of buffer-related problems when accessing raw
disk devices.

- Fix bug in dlclose.

- Don't set TZ environment variable in calls to tzset.

- Don't follow symlinks in calls to open if O_EXCL is
given.

- Fix deadlock and reentrancy problems in stdio functions. 
Fix
  append mode handling in stdio functions.

- Fix append mode bug when accessing files > 4 Gigs.

- Various fixes to stat/fstat/lstat functions (wrong
permission bits,
  timestamps, etc).

- Fix a deadlock problem in fork, as well as a crash on fork
after
  calling shmctl(IPC_RMID).

- Add thread-safety to mmap and to XSI IPC calls.

- Drop a non-sensical check in pthread_key_create.

- Encode special characters in /proc/registry key and value
names to
  avoid invalid character problems.

- Assorted fixes to cygpath.exe, cygcheck.exe, dumper.exe
and mkgroup.exe.

- Various bugfixes to printf/scanf function families.  Add
support for
  j, t, and z modifiers to scanf functions.

- Close security hole in tmpfile.

- Fix potential crashes in argz functions.

- Fix long-standing regression in rewind error handling.

- Support NULL output buffer in wcstombs.
