[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

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

From: Chip Salzenberg <chip@atlantic.net>
Files: MANIFEST Makefile.SH old_embed.pl old_global.sym

 		perl___ - cannot fork, can dynalink.
 	The build of the first one - perl - is rather convoluted, and
 	  requires a build of miniperl_.
+
+after 5.003_07:
+	custom tmpfile and tmpname which may use $TMP, $TEMP.
+	all the calls to OS/2 API wrapped so that it is safe to use
+		them under DOS (may die(), though).
+	Tested that popen works under DOS with modified PDKSH and RSX.
+	File::Copy works under DOS.
+	MakeMaker modified to work under DOS (perlmain.c.tmp and sh -c true).
