Don't ever mark the source binding of a link as new. This was an
attempt to work around problems with the linker, but the problem is in
the linker and not here; the linker should automatically generate the
source binding if it is missing.

Restructure packaging so that all runtime-system packages inherit from

the syntax from SYNTAX-TABLE/SYSTEM-INTERNAL.

Fine tune the code that decides when to use CPUID. For now, use it
only for Athlon model 1, 2, 3, or 4 processors. According to AMD, the
model 6 is OK, and perhaps the model 7 as well. The model 4 is known
to be bad, and models 1, 2, and 3 are probably bad too. No Intel
processors are known to be bad.

Change package system to conditionalize everything according to the
operating-system type. All output files are now OS-specific, e.g.
"runtime.pkg" produces output files "runtime-unx.{pkd,fre,crf}".
Package files can now use the conditionalization variable OS-TYPE.

Optimizer wasn't deleting unused procedure-valued bindings if the
procedure had side-effects. The bug fix to make top-level failure
continuations do backtracking prevented them from being substituted
properly; the substitution predicate was extended to allow this.
Also, some valuable substitutions weren't being seen because the
optimizers were being run in a fixed order. After the peephole
optimization is done, it reveals more possibilities for substitution.
So now the optimizers are re-run until nothing more can be done.

Change imap-url-mailbox to always be a string. The root "mailbox" is

specially when converting the URL to a string.

Fix some problems in the pointer optimization: pointers were being
incorrect elided across lambda expressions, and external pointer
bindings were being elided. The latter is fixed by introducing a
mechanism to distinguish internal identifiers, which eliminates the

Three fixes that together resolve the problem of compiling the XML
parser. (1) FOR-EACH-CALLEE! claimed to examine all of the callees,
but it wasn't looking at procedures called from descendant blocks that
had been disowned. (2) When removing dependent constraints, due to
closure, constraints that had indirect dependencies on the now-closed
procedure weren't being removed. (3) When adding undrifting
constraints due to closure contagion, it's wrong to constrain the
invocation block of a trivial closure.
