* 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.

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/gencgc.c
lisp/os-common.c
lisp/ppc-validate.h
lisp/purify.c
lisp/solaris-os.c
lisp/sparc-arch.c
lisp/sparc-validate.h
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.

.indent.pro.

work on Solaris 10. (Eventually, he gets a GC lossage).  But setting
-dynamic-space-size 256 works fine.  The difference is that the
default is 256 MB - 32 KB.

So change the default to just 256 MB.  We don't understand why the old
default causes funny things to happen on Solaris 10.

already had space for this but were only allocating 128 MB.  If we
want more, we'll have to move things around.)

o Increase the max heap space to 2816 MB from 2048 MB.  (This is about as
  much as we can do, since some space is needed for the C stack located
  at high memory.)

o Moved definition of SPARSE_BLOCK_SIZE from solaris-os.c to here, so
  we can use it in defining the sizes of the various spaces.
o With GENCGC, we can use the space that was allocated for dynamic
  space 1, so make it 2GB.  (Not that I've ever had to use that much
  space.)

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

is restored, a (supplied) initial function is invoked which can do whatever
kind of setup it wants.  This makes a saved lisp totally independent of the
location of the C stack.

sunos support code.

of those pages for something else.
