    temp commit, for pushing out of paranoia
    
    Given that things are working now more or less, I should push, just so
    this work isn't lost. I plan on rebasing this branch into sane patches
    at some point in the future, but we have releases to get out before
    then...

    srfi-4 vects are representable using bytevectors, not switched yet
    
    * libguile/bytevectors.h (SCM_BYTEVECTOR_INLINE_THRESHOLD)
      (SCM_BYTEVECTOR_INLINEABLE_SIZE_P): Move these to the .c file.
      (SCM_BYTEVECTOR_TYPE_HINT_NONE)
      (SCM_BYTEVECTOR_TYPE_HINT_U8)
      (SCM_BYTEVECTOR_TYPE_HINT_S8)
      (SCM_BYTEVECTOR_TYPE_HINT_U16)
      (SCM_BYTEVECTOR_TYPE_HINT_S16)
      (SCM_BYTEVECTOR_TYPE_HINT_U32)
      (SCM_BYTEVECTOR_TYPE_HINT_S32)
      (SCM_BYTEVECTOR_TYPE_HINT_U64)
      (SCM_BYTEVECTOR_TYPE_HINT_S64)
      (SCM_BYTEVECTOR_TYPE_HINT_F32)
      (SCM_BYTEVECTOR_TYPE_HINT_F64)
      (SCM_BYTEVECTOR_TYPE_HINT_C32)
      (SCM_BYTEVECTOR_TYPE_HINT_C64)
      (SCM_BYTEVECTOR_TYPE_HINT_LAST): New exciting type hints. Since
      bytevectors need to be able to print themselves, and srfi-4 will need
      to be able to create a typed bytevector, this knowledge must be shared
      between the two. It's internal API, though.
      (scm_c_take_bytevector): This internal func takes an additional arg,
      the type hint.
    
    * libguile/bytevectors.c (type_sizes, type_tags): Arrays for the unit
      sizes and #foo() tags for the various hinted types of byte vectors.
      (make_bytevector, make_bytevector_from_buffer, scm_c_take_bytevector):
      Take an extra type hint param. Callers adapted.
      (scm_i_shrink_bytevector): Fix shrinking for inlined bytevectors.
      (print_bytevector): Print hinted bytevectors appropriately. Neat :)
    
    * libguile/r6rs-ports.c: Adapt to scm_c_take_bytevector changes.

commit 4758ab8b5abdef807cffc2c84ba3ca99dfab68bf
Author: Andy Wingo <address@hidden>
Date:   Thu Jul 2 17:46:23 2009 +0200

    fix race in which some instruction name symbols could go unmarked
    
    * libguile/instructions.c: In loops, replace scm_op_last with
      SCM_VM_NUM_INSTRUCTIONS.
      (fetch_instruction_table): Protect the instruction symbols from
      collection. Before they were only marked by the name->opcode hash
      table, leading to races in which they could be collected.
      (scm_lookup_instruction_by_name): Protect the hash table earlier, as
      it's not actually a stack variable, since it's static.

commit 347637db2a7b62f69c11f3233627af9247c1b036
Author: Andy Wingo <address@hidden>

    fix bounds checks for the last element of bv-*-{ref,set}
    
    * libguile/vm-i-scheme.c (BV_FIXABLE_INT_REF, BV_INT_REF):
      (BV_FLOAT_REF, BV_FIXABLE_INT_SET, BV_INT_SET, BV_FLOAT_SET): Fix the
      bounds check for the last element.

    bytevectors have smob flags, and space for a type hint
    
    * libguile/bytevectors.h (SCM_F_BYTEVECTOR_INLINE):
      (SCM_F_BYTEVECTOR_READONLY):
      (SCM_BYTEVECTOR_INLINE_P):
      (SCM_BYTEVECTOR_READONLY_P):
      (SCM_BYTEVECTOR_TYPE_HINT): New preprocessor defines, within the
      "internal" section of the header. The new deal is that we will detect
      inline bytevectors by the flag instead of by the length. We reserve
      space for 8 flags, and the rest of the space (8 or 40 bits) is for the
      upcoming bytevector type hint.
    
    * libguile/bytevectors.c (make_bytevector_from_buffer, make_bytevector)
      (scm_c_take_bytevector): Simplify code.
      (scm_i_shrink_bytevector): Make sure to set the INLINE flag if needed.
      (free_bytevector): Don't free the contents if they are marked
      READONLY.

    remove deprecated functions from unif.c
    
    * libguile/unif.h:
    * libguile/unif.c: Remove deprecated functions.
    
    * module/ice-9/deprecated.scm: Remove array-related deprecated
      functions.
    
    * NEWS: Update.
