Hi folks,


I uploaded a new Cygwin test release 2.10.0-0.2

I'm planning for a release in early February.  Please test.

=======================================================================
TESTERS HEADS-UP:

  Cygwin 2.10.0 will come with a new gencat tool based on BSD code.

  The consequence is that the Cygwin test package collides with the
  catgets package in terms of the /usr/bin/gencat.exe binary.

  This will be rectified at 2.10.0 release time, but for now, just
  keep this in mind.
  
=======================================================================

What's new:
-----------

- New open(2) flags O_TMPFILE and O_NOATIME.

- scanf/wscanf now handle the POSIX %m modifier.

- scanf now handles the %l[ conversion.

- Improved hostprogs compatibility for cross-compiling the Linux kernel.
  New headers: <asm/bitsperlong.h>, <asm/posix_types.h>.

- Built-in implementation of Stack Smashing Protection compiler feature.
  New APIs: __stack_chk_fail, __stack_chk_guard.

- Built-in implementation of _FORTIFY_SOURCE guards for functions in
  <stdio.h>, <stdlib.h>, <string.h>, <strings.h>, <unistd.h>, <wchar.h>,
  <sys/poll.h>, and <sys/socket.h>.
  New APIs:  __chk_fail, __gets_chk, __memcpy_chk, __memmove_chk, __mempcpy_chk,
  __memset_chk, __snprintf_chk, __sprintf_chk, __stpcpy_chk, __stpncpy_chk,
  __strcat_chk, __strcpy_chk, __strncat_chk, __strncpy_chk, __vsnprintf_chk,
  __vsprintf_chk.

- Built-in implementation of POSIX.1-2001 message catalog support.
  New APIs: catclose, catgets, catopen.  New tool: gencat.

- New APIs: sigtimedwait, wmempcpy.


What changed:
-------------

- Standard headers no longer use macros to support K&R C.

- confstr(3) and getconf(1) accept LFS_CFLAGS, LFS_LDFLAGS, etc.

- The __always_inline and __nonnull macros in <sys/cdefs.h> are now
  compatible with glibc.

- Feature Test Macros improvements in <fcntl.h>, <limits.h>, <netdb.h>,
  <strings.h>, and <unistd.h>.
