Perl and crypt.h

[Alexey Sokolov]

Hi Achim,
I think perl package should depend on libcrypt-devel on x86_64.
Otherwise, here's error while embedding perl:

> In file included from /usr/lib/perl5/5.22/x86_64-cygwin-threads/CORE/op.h:635:0,
>                  from /usr/lib/perl5/5.22/x86_64-cygwin-threads/CORE/perl.h:3736,

It seems to works without libcrypt-devel on i686 though.
