The changes to lisp.h intended to enhance debugging on AIX broke
debugging when GCC 3.x is used to compile the code: I get "No symbol
"VALMASK" in current context." when xbacktrace is invoked.

So I reverted that part of the changes.  I hope there's a way to
define the relevant macros only for AIX, so that other platforms
aren't affected, certainly not during the pretest.
