Well, probably it should, but what actually happens is:
$ cat extensions.pl
#!perl -w
use strict;
use Config;
printf "%-24s", 'extensions';
my @types = qw(static_ext dynamic_ext nonxs_ext known_extensions);
my %lookup;
my %short;
foreach (@types) {
my $short = $_;
$short =~ s/_.*//;
$short{$_} = $short;
printf "%-8s", $short;
$lookup{$_} = {map {$_, 1} split/ /, $Config{$_}};
}
print "\n\n";
foreach my $ext (sort split / /, $Config{extensions}) {
printf "%-24s", $ext;
foreach (@types) {
printf "%-8s", $lookup{$_}{$ext} ? $short{$_} : '';
}
print "\n";
}
__END__

"extensions" is everything.
"known_extensions" = "static_ext" + "dynamic_ext"
"extensions" = "nonxs_ext" + "known_extensions"
which isn't logical, but I suspect is due to something historical.
