Downloaded a package onig-5.9.2.tar.gz from the site:
http://www.geocities.jp/kosako3/oniguruma/
and expanded its content in this directory. Makefile.bcc is a makefile for
Borland C++ that I created here.

To create a library for Win32, execute the following commands in this
directory.

$ make -f Makefile.bcc setup
$ make -f Makefile.bcc clean
$ make -f Makefile.bcc
