Rename all ChangeLog files to ChangeLog-2011.
We already modify gpgme.h per playform and thus we can also get rid of
some #ifdefs. The change does not change anything for current
platforms but should do the right think for W64.
Note that as per MS specs ssize_t is to be defined as LONG_PTR which
translates to a long on 32 bit platforms and to __int64 on 64 bit
Windows platforms. We already used long in the past. There seems to
be a problem with some versions of mingw32 which includes a ssize_t
type typedefed to int. O(n 32 bit W32 platforms int and long are
identically.
* Makefile.am (EXTRA_DIST): Include autogen.sh
* autogen.sh: Added the usual code to build for W32 (--build-w32).
* configure.ac: Fixed the mingw32 host string, removed OS/2 stuff.
(HAVE_DRIVE_LETTERS): Removed.
(HAVE_W32_SYSTEM): Added.
(AC_GNU_SOURCE): New to replace the identical AH_VERBATIM.
(AH_BOTTOM): Added.
* w32-util.c (_gpgme_get_gpg_path, _gpgme_get_gpgsm_path): Do not
cast away type checks.
* io.h [W32]: Do not include stdio.h. If it is needed do it at
the right place.
* data.h [W32]: Removed kludge for EOPNOTSUP.
* data.c, data-compat.c [W32]: Explicitly test for it here.
