+
+ * generic/tclInt.decls:
+ * generic/tclTest.c:
+ * generic/tclUtil.c:
+ * win/tclWin32Dll.c: fixed link error due to direct access by
+ tclTest.c to the MODULE_SCOPE tclPlatform global: renamed existing
+ TclWinGetPlatform() accessor to TclGetPlatform() and moved it to
+ generic code so that it can be used by on all platforms where
+ MODULE_SCOPE is enforced.
+
+ * macosx/tclMacOSXBundle.c:
+ * unix/tclUnixInit.c:
+ * unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable
+ and added test of CoreFoundation availablility to allow building on
+ ppc64, replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for
+ availability of Tiger or later OSSpinLockLock API.
+
+ * unix/tclUnixNotfy.c:
+ * unix/Makefile.in:
+ * macosx/tclMacOSXNotify.c (new file): when CoreFoundation is
+ available, use new CFRunLoop based notifier: allows easy integration
+ with other event loops on Mac OS X, in particular the TkAqua Carbon
+ event loop is now integrated via a standard tcl event source (instead
+ of TkAqua upon loading having to finalize the exsting notifier and
+ replace it with its custom version). [Patch 1202052]
+
+ * tests/unixNotfy.test: don't run unthreaded tests on Darwin
+ since notifier may be using threads even in unthreaded core.
+
+ * unix/tclUnixPort.h:
+ * unix/tcl.m4 (Darwin): test for thread-unsafe realpath durning
+ configure, as Darwin 7 and later realpath is threadsafe.
+
+ * macosx/Makefile: enable configure caching.
+
+ * unix/configure.in: wrap tclConfig.h header in #ifndef _TCLCONFIG so
+ that it can be included more than once without warnings from gcc4.0
+ (as happens e.g. when including both tclInt.h and tclPort.h)
+
+ * macosx/tclMacOSXBundle.c:
+ * unix/tclUnixChan.c:
+ * unix/tclLoadDyld.c:
+ * unix/tclUnixInit.c: fixed gcc 4.0 warnings.
+
+ * unix/configure: autoconf-2.59
+ * unix/tclConfig.h.in: autoheader-2.59
+
+ * generic/tclIntDecls.h:
+ * generic/tclIntPlatDecls.h:
+ * generic/tclStubInit.c: make genstubs
