* tests/fCmd.test:

	* unix/tclUnixFCmd.c (TraverseUnixTree): added option to rewind()
	the readdir() loop whenever the source hierarchy has been modified
	by traverseProc (e.g. by deleting files); this is required to ensure
	complete traversal of the source hierarchy on certain filesystems
	like HFS+. Added test for failing recursive delete on Mac OS X that
	was due to this. [Bug 1034337]

	* generic/tclListObj.c (Tcl_ListObjReplace): use memmove() instead
	of manual copy loop to shift list elements. Decreases time spent in
	Tcl_ListObjReplace() from 5.2% to 1.7% of overall runtime of
	tclbench on a ppc 7455 (i.e. 200% speed increase). [Patch 1064243]

	* generic/tclHash.c: hoisted some constant pointer dereferences out
	of loops to eliminate redundant loads that the gcc optimizer didn't
	deal with. Decreases time spend in Tcl_FindHashEntry() by 10% over a
	full run of the tcl testuite on a ppc 7455. [Patch 1064243]

	* tests/fileName.test:
	* tests/fileSystem.test:
	* tests/io.test:
	* tests/msgcat.test:
	* tests/tcltest.test:
	* tests/unixInit.test: fixed bugs causing failures when running
	tests with -tmpdir arg not set to working dir.

	* macosx/Makefile: corrected path to html help inside framework.
	Prevent parallel make from building several targets at the same
	time.

	* macosx/tclMacOSXFCmd.c (struct fileinfobuf): force struct to be
	packed to prevent failures when builing with -malign=natural.
