Changes to support building on Mac OS X 10.6.  When compiled on 10.6,
the resulting binary still works on 10.5.

lisp/Config.x86_darwin:
o Add -m32 flag to build and link a 32-bit binary.

lisp/Darwin-os.h:
o Include <sys/ucontext.h> instead of <ucontext.h> to get rid of the
  error about deprecated functions in ucontext.h.

lisp/gencgc.h:
o Mac OS X defines PAGE_SIZE in a header and that conflicts with our
  name.  Rename our PAGE_SIZE to GC_PAGE_SIZE.

lisp/gencgc.c:
o Rename PAGE_SIZE to GC_PAGE_SIZE.

Switch the FreeBSD port to use the common floating point trap handling
code.  Rather than introduce a new FreeBSD case to the x86 sigcontext
member accessor routines, collapse all of the system specific routines
down to a common set of routines.

* code/debug-int.lisp - Disable some Darwin-specific code to debug
  NULL mcontext pointers.

* code/float-trap.lisp - Remove ancient FreeBSD-specific code for
  handling floating point signals.

* code/macros.lisp, code/sap.lisp, compiler/saptran.lisp - Include the
  SAP-REF-LONG setter by default on the x86.

* code/x86-vm.lisp - Remove operating system specific sigcontext
  definitions and sigcontext accessors.  Define the alien sigcontext
  as a system area pointer.  Replace the sigcontext accessors with
  foreign function calls that mask the complexity of the underlying
  sigcontext member access.

* compiler/x86/float.lisp - Unconditionally define STORE-LONG-FLOAT.
  This function is used by the %SET-SAP-REF-LONG VOP that underlies
  the SAP-REF-LONG setter.

* compiler/x86/sap.lisp - Unconditionally define %SET-SAP-REF-LONG.
  In the case where there is not a distinct LONG-FLOAT type, admit
  DOUBLE-FLOAT values instead.  The x87 automatically widens values
  pushed onto stack.  This mirrors the behavior of the SAP-REF-LONG
  VOP.

* lisp/Darwin-os.c, lisp/Linux-os.c - Define functions to access
  sigcontext members of interest to Lisp.  Delete the sc_reg function
  and replace its uses with os_sigcontext_reg which is more suitably
  typed.

* lisp/FreeBSD-os.c - Define functions to access sigcontext members of
  interest to Lisp.  We need to be careful about the SSE and non-SSE
  cases for retrieving x87 registers from the saved machine state.
  Define a low-level SIGFPE handler to intercept floating point traps
  and restore the cleared status word bits based on the signal code.
  Get rid of sc_reg for the reasons noted above.

* lisp/Darwin-os.h, lisp/FreeBSD-os.h - Declare the restore_fpu
  function and define a specialized RESTORE_FPU macro.  Remove the
  sc_reg prototype.

* lisp/Linux-os.h - Remove the sc_reg prototype.

* lisp/os.h - Add prototypes for the new os_sigcontext functions.

* lisp/x86-lispregs.h - Redefine SC_REG and SC_PC to expand out to the
  new os_sigcontext functions.  Redfine SC_SP to expand out to SC_REG.
  Eliminate all platform-specific defintions of SC_PC and SC_SP.

First merge of the C side of the OS X/Darwin port.  Besides adding Darwin
versions of all the required things, this commit separates the
interrupt handler proper (now interrupt_handle_now_handler) from the
actual work-horse (interrupt_handle_now), which is now only ever called
from the two interrupt handlers, interrupt_handle_now_handler and
maybe_now_maybe_later.  This follows similar changes in SBCL, and is in
fact needed in order to properly use sigreturn in signal handlers, as
required to work around a problem with the G5.
