Hi Cygwin friends and users,

I released another version of Cygwin.  The version number is 2.1.0-1.

What's new:

- Handle pthread stacksizes as in GLibc:  Default to RLIMIT_STACK resource.
  Allow to set RLIMIT_STACK via setrlimit.  Default RLIMIT_STACK to value
  from executable header as described on
  Default stacksize to 2 Megs in case RLIMIT_STACK is set to RLIM_INFINITY.

- First cut of an implementation to allow signal handlers running on an
  alternate signal stack.
- New API sigaltstack, plus definitions for SA_ONSTACK, SS_ONSTACK, SS_DISABLE,

- New API: sethostname.

Bug Fixes

- Enable non-SA_RESTART behaviour on threads other than main thread.

- Fix fork failing after the parent recovered from a stack overflow.

- Fix a crash on 64 bit XP/2003 when opening /proc/$PID/maps.

- Apparently on some Windows systems timezones differ in case
  from the standard.  Fix the tzset tool to check case-insensitive.
