[64bit] Missing library causing build of perl-PAR-Packer to fail

[Ken Brown]

In order to build biber.exe, I need to build the perl module 
PAR::Packer.  The build fails as follows:

g++ main.o ppresource.coff -s    -Wl,--enable-auto-import 
-Wl,--export-all-symbols -Wl,--enable-auto-image-base -fstack-protector 
  -L/usr/lib/perl5/5.14/x86_64-cygwin-threads/CORE -lperl -ldl -lcrypt 
-o ./par.exe
main.o: In function `xs_init':
/usr/src/debug/perl-PAR-Packer-1.013-14/myldr/perlxsi.c:17: undefined 
reference to `boot_Win32CORE'

On 32-bit Cygwin, boot_Win32CORE is provided by the library 
/usr/lib/perl5/5.14/i686-cygwin-threads-64int/auto/Win32CORE/Win32CORE.a. 
But on 64-bit Cygwin the corresponding library is missing from 
/usr/lib/perl5/5.14/x86_64-cygwin-threads/auto/Win32CORE.  Can we get a 
new build of perl that includes it?

Thanks.

P.S. My attempt to build perl-PAR-Packer is based on Yaakov's cygport 
file in Cygwin Ports.  This includes a patch for version 1.013 of 
PAR::Packer.  Version 1.014 is available, and I would rather build that 
version, but it's not obvious to me how to adapt the patch.  Yaakov, 
could you help me with that?
