Cygwin上のperl5.8.8のperlccを使ってperlスクリプトを
exe化しようと思う。
普通に実行すると下記のようにエラーが。
$ perlcc work/make_hash_list2.pl

-Bオプションをつけると、コンパイルできた。
$ perlcc -B -o work/kkk.exe test.pl
⇒cygwinでは実行できるが、windowsからは実行できなかった。
この実行形式はcygwinの上に載ったものだからだ。

の情報を元に、perlccでソースファイルを作成し、gccで--mno-cygwinオプションを
つけてコンパイルすることを試したが、山ほどworningがでるのでやめた。

perlcc自体信頼性は高くない模様。Cygwin環境で実現したかったが一旦あきらめることにする。
