Subject: 2008-02-12  Frank Ch. Eigler  <fche@elastic.org>

	* systemtap.context/context.exp: Build temporary modules under
	build tree, to tolerate read-only source trees.
	* {args,backtrace,pid}.tcl: Corresponding changes.
	* systemtap_test_module2.c: Add a bunch of asm("")'s to prevent
	inlining even better than noinline does.
