* Get rid of the RCS Header stuff.  They're meaningless in git.
 * Add public domain comment to some of the files if the only comment
   was the RCS header.

sunos-os.h:
o Update HANDLER_ARGS to match definition used in sigaction.
o Define os_context_t

lisp.c:
solaris-os.c:
sparc-arch.c:
o Use os_context_t as needed.

Make the size of all spaces configurable from the command line.

code/commandline.lisp:
o Define the switches so lisp doesn't complain.

general-info/lisp.1:
o Document new switches.

general-info/release-20c.txt:
o Update

lisp/Darwin-os.c
lisp/FreeBSD-os.c
lisp/Linux-os.c
lisp/NetBSD-os.c
lisp/backtrace.c
lisp/cgc.c

lisp/x86-validate.h:
lisp/validate.c
o Basically rename CONTROL_STACK_SIZE, BINDING_STACK_SIZE,
  READ_ONLY_SPACE_SIZE, and STATIC_SPACE_SIZE to control_stack_size,
  binding_stack_size, read_only_space_size, and static_space_size,
  respectively.

lisp/coreparse.c
o Check the space size in the core file against the allocated size.
  If the allocated space is too small, print an error message and
  exit.

lisp/globals.c
o Define new variables for the allocated size of spaces.

lisp/globals.h
o Declare the new variables for the size of the spaces.

lisp/lisp.c
o Set the default values of the spaces.
o Parse the new command-line flags and set the space sizes.

lisp/sunos-os.c:
o Added os_init0 (that we forgot last time).

lisp/x86-assem.S:
o Change $CONTROL_STACK_END to GNAME(control_stack_end) to get the
  correct end of the stack.

On Linux, os_init can re-exec lisp to set up the correct personality.
Not normally a problem, but if any output happens before os_init is
called, the output appears to happen twice.  So add os_init0 to do
this early on, before any output.  This is a bit of a kludge.

lisp/lisp.c:
o Call os_init0 early in main.

lisp/Linux-os.c:
o Move the personality stuff from os_init to os_init0.

lisp/Darwin-os.c:

lisp/mach-os.c:
lisp/osf1-os.c:
lisp/solaris-os.c:
lisp/sunos-os.c:
o Add dummy implementation of os_init0.  These OSes don't (currently)
  need anything special.

lisp/os.h:
o Declare os_init0.

registers. The test is a stub on everything except NetBSD for now.

Among other things, this makes tracing work with x87 floating-point
values.

Solaris/x86.  There should be no functional changes for either other
x86 ports or for the sparc port.

o Follow CMUCL coding style.
o Argv and envp are const char*.

o argv and envp are const char *.

    When run on a kernel compiled without COMPAT_BRK CMUCL segfaults,
    so I copied the kludge used by SBCL - check the current
    personality, and if necessary, enable ADDR_NO_RANDOMIZE and
    re-exec itself.

Linux-os.c:
o Check for personality and rexec if necessary.

os.h:
o New prototype for os_init needed because it needs argv and envp.

systems that do not populate /dev with BSD pseudo-terminal devices.

void keyword to specify empty parameter lists.

failure instead of -1.

interrupt_handle_now directly.  (For debugging purposes.)

.indent.pro.

* gencgc.h:  Add declaration for alloc.

* solaris-os.c:
  o Include interrupt.h
  o Clean up some printf warnings, apply appropriate casts for
    converting address to longs and vice versa.

* sparc-arch.c:
  o Include gencgc.h, breakpoint.h, interr.h to declare some functions
    for us.
  o Instructions are ints, not longs.  (64-bitness cleanup.)
  o handle_breakpoint and handle_function_end_breakpoint were not
    called with the right second arg.

* sunos-os.h:
  o Declare flush_icache and save_context.

weren't caused by a write-protected heap.  Requested by Lynn Quam.

print out a message saying so instead of silently dumping core.
(Requires an alternate signal stack.)

because there is no dynamic 1 space.  (Minor opt.)

because there is no dynamic_1 space with GENCGC.  This was causing CMUCL to
segfault when using more than 512 MB of heap.

  - fix a signed/unsigned cast bug that was prevented the
    auto-gc-trigger from functioning correctly when using certain
    dynamic-space sizes (for platforms that don't have an internal gc
    trigger).

  - added a few #include files to avoid compiler warnings

  - changed some #ifdef semantics: DEBUG activates additional
    assertions, and PRINTNOISE activates debugging statements.

	* lisp/sunos-os.h (PROTECTION_VIOLATION_SIGNAL): Define it for
	stack-checking.

	* lisp/solaris-os.c (segv_handler): Add stack-checking support for
	Solaris.

	* lisp/os.h (os_control_stack_overflow): Give a type name to the
	zone enums (mostly for the debugger).

	* lisp/os-common.c (guard_zones): Add stack-checking support for
	Solaris.
	(os_control_stack_overflow): Add stack-checking support for
	Solaris.

	* lisp/interrupt.c (build_fake_control_stack_frame): New function
	for building a stack frame without the foreign call stuff.  Used
	for stack checking.
	(interrupt_install_low_level_handler): Only need to install
	alternate signal stack for x86.

	* lispinit.lisp:
	(scrub-control-stack): Rename to %scrub-control-stack to match x86
	version so control stack guard is done.

	* parms.lisp (static-symbols): Added new static symbols for
	control stack checking.

whatever dlsym returns.

o Make new-genesis save target-foreign-linkage-table-size to
  internals.h.

o Remove unused empty_fd stuff (Noted by Hallvard B Furuseth
  <h.b.furuseth@usit.uio.no>).
o Do some testing of addresses in valid_addr, stolen from Linux-os.c.
o Clean up some compiler warnings about passing pointers without casts.
