* 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.
