[inseparable changes from patch from perl5.003_07 to perl5.003_08]

 CORE LANGUAGE CHANGES

Subject: Bitwise op sign rationalization
From: Chip Salzenberg <chip@atlantic.net>
Files: op.c opcode.pl pod/perlop.pod pod/perltoc.pod pp.c pp.h pp_hot.c proto.h sv.c t/op/bop.t

    Make bitwise ops result in unsigned values, unless C<use
    integer> is in effect.  Includes initial support for UVs.

Subject: Defined scoping for C<my> in control structures
From: Chip Salzenberg <chip@atlantic.net>
Files: op.c perly.c perly.c.diff perly.h perly.y proto.h toke.c

    Finally defines semantics of "my" in control expressions,
    like the condition of "if" and "while".  In all cases, scope
    of a "my" var extends to the end of the entire control
    structure.  Also adds new construct "for my", which
    automatically declares the control variable "my" and limits
    its scope to the loop.

Subject: Fix ++/-- after int conversion (e.g. 'printf "%d"')
From: Chip Salzenberg <chip@atlantic.net>
Files: pp.c pp_hot.c sv.c

    This patch makes Perl correctly ignore SvIVX() if either
    NOK or POK is true, since SvIVX() may be a truncated or
    overflowed version of the real value.

Subject: Make code match Camel II re: functions that use $_
From: Paul Marquess <pmarquess@bfsec.bt.co.uk>
Files: opcode.pl

Subject: Provide scalar context on left side of "->"
From: Chip Salzenberg <chip@atlantic.net>
Files: perly.c perly.y

Subject: Quote bearword package/handle FOO in "funcname FOO => 'bar'"
From: Chip Salzenberg <chip@atlantic.net>
Files: toke.c

From: Gurusamy Sarathy <gsar@engin.umich.edu>

Subject: Complete EMBED, including symbols from interp.sym
From: Chip Salzenberg <chip@atlantic.net>
Files: MANIFEST embed.pl ext/DynaLoader/dlutils.c ext/SDBM_File/sdbm/sdbm.h global.sym handy.h malloc.c perl.h pp_sys.c proto.h regexec.c toke.c util.c x2p/Makefile.SH x2p/a2p.h x2p/handy.h x2p/util.h

    New define EMBEDMYMALLOC makes embedding total by
    avoiding "Mymalloc" etc.

Subject: Support old embedding for people who want it
From: Chip Salzenberg <chip@atlantic.net>
Files: MANIFEST Makefile.SH old_embed.pl old_global.sym
