Updated: Cygwin 1.7.19

Hi Cygwin friends and users,

I just released Cygwin 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

- 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.

- 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.

- Fix a build problem resulting in Cygwin functions picking up the wrong

- Fix an incorrect condition which breaks fork after all dlopen'ed DLLs
  have already been dlclose'd.

- Fix buggy usage of NtReadFile when reading from device under /proc/sys.

- Fix an include in <cygwin/if.h> to avoid circular dependency.

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

Have fun,
