* Run configure as usual.
* Run "make distcheck"
* Build and test the new tarball (best on a different machine).
* [1.4 only] Build and test the W32 version.
* Build and test the W32 version.
* Using the final test build run a "make -C doc online".

2007-08-22 Werner Koch <wk@g10code.com>
Updated estream from libestream.
* estream.c (mem_malloc, mem_realloc, mem_free): New. Use them
instead of the ES_MEM_foo.
* estream.c (estream_cookie_mem): Remove members DONT_FREE,
APPEND_ZERO, PTR and SIZE. Add MEMORY_LIMIT. Put GROW into a new
FLAGS struct.
(es_func_mem_create): Remove APPEND_ZERO, DONT_FREE, PTR and
SIZE. Add MEMORY_LIMIT.
(es_func_mem_write, es_func_mem_seek, es_func_mem_destroy): Revamp.
(es_open_memstream): Change API to just take a memory limit and a
mode argument. Rename to ..
(es_fopenmem): .. this.
(HAVE_W32_SYSTEM) [_WIN32]: Define if not defined.
(tmpfd) [W32]: Implement directly using the W32 API.
(es_fgets): Rewrite without using doreadline.
2007-08-21 Werner Koch <wk@g10code.com>
* sysutils.c (gnupg_tmpfile): New.
* t-sysutils.c: New.
* Makefile.am (module_tests): Add t-sysutils.
2007-08-20 Werner Koch <wk@g10code.com>
* exechelp.c [W32]: Redefine X_OK to F_OK.
2007-08-16 Werner Koch <wk@g10code.com>
