-    #	  and a_entry fields.
-    # The following compilation should succeed if and only if either sys/exec.h
-    # or a.out.h is usable for the purpose.

-    # Note that the modified COFF format used on MIPS Ultrix 4.x is usable; the

+
+	* tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for

+	(TEA_MAKE_LIB): Prepend 'lib' for Windows-gcc configs.
+
+2006-03-07  Joe English  <jenglish@users.sourceforge.net>
+
+	* tcl.m4: Set SHLIB_LD_FLAGS='${LIBS}' on NetBSD,

+
+2006-01-25  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	*** Bump to TEA version 3.5 ***
+
+	* tcl.m4: keep LD_SEARCH_FLAGS and CC_SEARCH_FLAGS synchronous
+	with core tcl.m4 meaning.
+
+2006-01-24  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (Darwin): use makefile variable LDFLAGS_DEFAULT instead of
+	LDFLAGS in SHLIB_LD, to ensure linker flags in sampleextension Makefile
+	are picked up. [Bug 1403343]
+
+2006-01-23  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: add C:/Tcl/lib and C:/Progra~1/Tcl/lib dirs to check for
+	*Config.sh on Windows. [Bug 1407544]
+
+2006-01-23  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (Darwin): for Tk extensions, remove -arch ppc64 from CFLAGS
+	like in the Tk configure, as neither TkAqua nor TkX11 can be built for
+	64bit at present (no 64bit GUI libraries).
+
+2006-01-22  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: restore system=windows on Windows.
+	Remove error if 'ar' isn't found (it may not be on Windows).
+	Do not add -lxnet or define _XOPEN_SOURCE on HP-UX by default.
+	Ensure the C|LDFLAGS_DEFAULT gets the fully sub'd value at
+	configure time.
+
+2006-01-10  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4: add caching, use AC_CACHE_CHECK instead of AC_CACHE_VAL
+	where possible, consistent message quoting, sync relevant
+	tcl/unix/tcl.m4 HEAD changes and gratuitous formatting differences
+	(notably sunc removal of support for for ancient BSD's, IRIX 4,
+	RISCos and Ultrix by kennykb), Darwin improvements to
+	TEA_LOAD_*CONFIG to make linking work against Tcl/Tk frameworks

+
+2005-12-05  Don Porter  <dgp@users.sf.net>

+
+2005-12-02  Jeff Hobbs  <jeffh@ActiveState.com>
+

+2005-12-01  Daniel Steffen  <das@users.sourceforge.net>
+

+
+2005-11-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4:  *** Bump to TEA version 3.4 ***
+	Add Windows x64 build support.
+	Remove TEA_PATH_NOSPACE and handle the problem with ""s where
+	necessary - the macro relied on TCLSH_PROG which didn't work for
+	cross-compiles.
+
+2005-11-27  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (Darwin): add 64bit support, add CFLAGS to SHLIB_LD to
+	support passing -isysroot in env(CFLAGS) to configure (flag can't
+	be present twice, so can't be in both CFLAGS and LDFLAGS during
+	configure), don't use -prebind when deploying on 10.4.
+	(TEA_ENABLE_LANGINFO, TEA_TIME_HANDLER): add/fix caching.
+
+2005-10-30  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4: fixed two tests for TEA_WINDOWINGSYSTEM = "aqua" that
+	should have been for `uname -s` = "Darwin" instead; added some
+	missing quoting.
+	(TEA_PROG_TCLSH, TEA_PROG_WISH): fix incorrect assumption that
+	install location of tclConfig.sh/tkConfig.sh allows to determine
+	the tclsh/wish install dir via ../bin. Indeed tcl/tk can be
+	configured with arbitrary --libdir and --bindir (independent of
+	prefix) and such a configuration is in fact standard with Darwin
+	framework builds. At least now also check ${TCL_PREFIX}/bin
+	resp. ${TK_PREFIX}/bin for presence of tclsh resp. wish (if tcl/tk
+	have been configured with arbitrary --bindir, this will still not
+	find them, for a general solution *Config.sh would need to contain
+	the values of bindir/libdir/includedir passed to configure).
+
+2005-10-07  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: Fix Solaris 5.10 check and Solaris AMD64 64-bit builds.
+
+2005-10-04  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_PRIVATE_TCL_HEADERS): add / to finish sed macro
+	(TEA_ENABLE_THREADS): don't check for pthread_attr_setstacksize func
+
+2005-09-13  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: *** Update to TEA version 3.3 ***
+	define TEA_WINDOWINGSYSTEM in TEA_LOAD_TKCONFIG.
+	Make --enable-threads the default (users can --disable-threads).
+	Improve AIX ${CC}_r fix to better check existing ${CC} value.
+	Do the appropriate evals to not require the *TOP_DIR_NATIVE vars
+	be set for extensions that use private headers.
+	Make aqua check for Xlib compat headers the same as win32.
+
+2005-07-26  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH,
+	TEA_PROG_WISH, TEA_BUILD_WISH): Remove
+	TEA_BUILD_TCLSH and TEA_BUILD_WISH because
+	of complaints that it broke the build when
+	only an installed version of Tcl was available
+	at extension build time. The TEA_PROG_TCLSH and
+	TEA_PROG_WISH macros will no longer search the
+	path at all. The build tclsh or installed
+	tclsh shell will now be found by TEA_PROG_TCLSH.
+
+2005-07-24  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH,
+	TEA_PROG_WISH, TEA_BUILD_WISH):
+	Split confused search for tclsh on PATH and
+	build and install locations into two macros.
+	TEA_PROG_TCLSH and TEA_PROG_WISH search the
+	system PATH for an installed tclsh or wish.
+	The TEA_BUILD_TCLSH and TEA_BUILD_WISH
+	macros determine the name of tclsh or
+	wish in the Tcl or Tk build directory even
+	if tclsh or wish has not yet been built.
+	[Tcl bug 1160114]
+	[Tcl patch 1244153]
+
+2005-06-23  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (TEA_PRIVATE_TK_HEADERS): add ${TK_SRC_DIR}/macosx to
+	TK_INCLUDES when building against TkAqua.
+
+	* tcl.m4 (TEA_PATH_X): fixed missing comma in AC_DEFINE
+
+	* tcl.m4: changes to better support framework builds of Tcl and Tk out
+	of the box: search framework install locations for *Config.sh, and if in
+	presence of a framework build, use the framework's Headers and
+	PrivateHeaders directories for public and private includes. [FR 947735]
+
+2005-06-18  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to
+	ensure we can always relocate binaries with install_name_tool.
+
 2005-06-04  Daniel Steffen  <das@users.sourceforge.net>
 
 	* tcl.m4 (TEA_PATH_X): for TEA_WINDOWINGSYSTEM == aqua, check if xlib
