src/lisp/gencgc.c:
o Save and restore the FPU state in alloc().

src/compiler/x86/float-sse2.lisp
src/compiler/x86/float.lisp
src/compiler/x86/move.lisp
src/compiler/x86/sap.lisp:
o Don't need to use :save-p anymore because the allocation routine
  saves an live registers anyway.  This improves code generation as
  well.

src/general-info/release-20d.txt:
o Update.

stack space to hold the SSE2 state.  (Forgot to add extra bytes for
16-byte alignment!)

src/lisp/x86-assem.S:
o Remove the (now) unused alloc_to_<reg> functions.

src/compiler/x86/macros.lisp:
o Simplify the not-inline-allocation to use the same routines as
  inline allocation.

src/bootfiles/20c/boot-2012-07-1-x86-cross.lisp:
o X86 cross-compile script

src/compiler/x86/macros.lisp:
o New inline-allocation to call our new overflow routine.

src/lisp/x86-assem.S:
o New alloc_overflow routine.

src/tools/cross-scripts/cross-x86-x86.lisp:
o Export all symbols in VM that are external symbols in OLD-VM with
  the corresponding symbol name.

point operations should occur in allocation or GC now, except when
printing stats.

src/compiler/main.lisp:
o Remove special treatment of EXPORT (and others) in the compiler.  I
  think we only need to treat IN-PACKAGE and DEFPACKAGE specially.

src/contrib/defsyste/defsystem.lisp:
o Add FIND-SYSTEM to the defpackage export list for MAKE.

src/tools/hemcom.lisp:
o Add defpackage for hemlock-internals since export no longer has the
  compile-time effect.

o Clean up reader conditionals in MAKE-FD-STREAM.
o Add dummy %SET-FD-STREAM-EXTERNAL-FORMAT for non-unicode.

Patch from Douglas.

   external format like {{{:DOS}}} or {{{:MAC}}}.

src/code/float-trap.lisp:
o Clear current and accrued exception bits that match any new enabled
  exceptions specified by :traps.

o Update.
