Win32 PerlIO intermediate state now working as expected.

  - In current state we are still using C runtime in text/binary
           mode and "crlf" layer is just a dummy (clone of perlio buffer layer).
  - PERLIO=stdio and PERLIO=unix pass all expected tests.
         - PERLIO=perlio fails t/lib/dprof.t because Dprof.xs calls PerlIO_tell()
           and PerlIO_seek() and the dummy crlf layer is not making adjustments
           for CRLF translation happening in C runtime. All other tests pass.

       Added note to README.win32 to point out the snags of doing a perl build
       with Norton AntiVirus turned on.

       Tweaked t/pragma/warnings.t so that when run stand-alone you can tell
       which file a fail comes from.

       Updated "canned" config.h to match the one generated.

 =head1 BUGS AND CAVEATS
 
+Norton AntiVirus interferes with the build process, particularly if 
+set to "AutoProtect, All Files, when Opened". Unlike large applications 
+the perl build process opens and modifies a lot of files. Having the  
+the AntiVirus scan each and every one slows build the process significantly.
+Worse, with PERLIO=stdio the build process fails with peculiar messages
+as the virus checker interacts badly with miniperl.exe writing configure 
+files (it seems to either catch file part written and treat it as suspicious,
+or virus checker may have it "locked" in a way which inhibits miniperl
+updating it). The build does complete with 
+   
+   set PERLIO=perlio
+
+but that may be just luck. Other AntiVirus software may have similar issues.

 Some of the built-in functions do not act exactly as documented in
 L<perlfunc>, and a few are not implemented at all.  To avoid
 surprises, particularly if you have had prior exposure to Perl
