The default NetBSD package manager is pkgsrc and it installs Perl along other third party programs under custom and configurable prefix. The default prefix for binary prebuilt packages is /usr/pkg, and the Perl executable lands in /usr/pkg/bin/perl. This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's the most portable solution that should work for almost everybody. Perl's executable is detected automatically. This change switches -w option passed to the executable with more modern "use warnings;" approach. There is no functional change to the default behavior. While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?). Signed-off-by: Kamil Rytarowski <n54@gmx.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

# you do have real dups and do not have them under #ifdef's. You
|
|
# could also just review the results.
