$ cygcheck /usr/bin/perl
and
$ ldd /usr/bin/perl'
did not show any error

but I "reinstalled" all packages listed in 
$ cygcheck -i --deps perl
=> cygwin, libcrypt2, libdb18.1, libgcc1, libgdbm6, libgdbm_compat4, perl5_040, perl_base, zlib0

after the reinstall, perl works again

$ perl -v

This is perl 5, version 40, subversion 2 (v5.40.2) built for x86_64-cygwin-threads-multi
(with 3 registered patches, see perl -V for more detail)

$ echo 'print "Hello Perl\n"' | perl
Hello Perl

thanks a lot!
