newlib-cygwin/winsup/cygwin/release/1.7.19

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

- Drop support for Windows 2000 and Windows XP pre-SP3.

- Add support for building a 64 bit version of Cygwin on x86_64 natively.

- Add support for creating native symlinks (CYGWIN=winsymlinks:native or
  CYGWIN=winsymlinks:nativestrict).

- Add support for the AFS filesystem.

- Preliminary support for mandatory locking via fcntl/flock/lockf, using
  Windows locking semantics.  New F_LCK_MANDATORY fcntl command.

- New APIs: __b64_ntop, __b64_pton, arc4random, arc4random_addrandom,
  arc4random_buf, arc4random_stir, arc4random_uniform.

Bug fixes:
----------

- getgrouplist now always creates a group list, even if it's empty.
  Fixes: http://cygwin.com/ml/cygwin/2013-05/msg00157.html

- In fork, call CreateProcessW with the same command line as the parent
  process.  This seems to make sure the stack is created in the same
  memory location as in the parent.
  Fixes: http://cygwin.com/ml/cygwin/2013-05/msg00340.html

- Fix a build problem resulting in Cygwin functions picking up the wrong
  new/delete.
  Fixes: http://cygwin.com/ml/cygwin/2013-05/msg00331.html

- Fix an incorrect condition which breaks fork after all dlopen'ed DLLs
  have already been dlclose'd.
  Fixes: http://cygwin.com/ml/cygwin/2013-05/msg00376.html

- Fix buggy usage of NtReadFile when reading from device under /proc/sys.
  Fixes: http://cygwin.com/ml/cygwin/2013-05/msg00392.html

- Fix an include in <cygwin/if.h> to avoid circular dependency.
  Fixes: http://cygwin.com/ml/cygwin/2013-05/msg00451.html

- Fix a hang on exit when calling pthread_join in global desctructor.
