* THANKS: Changes from stable branch.

* configure.ac: Check for ctermid().  From Werner on stable
branch.

* configure.ac (GPGKEYS_LDAP,GPGKEYS_HKP): Add $EXEEXT.  From
Werner on stable branch.

* configure.ac (try_gettext): Remove special case for cygwin.
This removes all the DOS specific macros and let Cygwin work like
a real OS.  Needs a couple of changes elsewhere but after all,
GnuPG presents itself much more like a Posix program and can be
used in a full Cygwin environment; e.g. used along with mutt.
Changes suggested by Volker Quetschke.  From Werner on stable
branch.

* acinclude.m4 (GNUPG_SYS_NM_PARSE): Allow for underscore in test
symbols.  Useful for Cygwin builds.
(GNUPG_SYS_SYMBOL_UNDERSCORE): Don't hardwire to yes for Cygwin.
From Werner on stable branch.

* README: Add an installation note for Darwin 6.1.  From Werner on
stable branch.
