* This DLL is a simple direct translation of C versions of MT(mt19937-2.c, cokus.c, mt19937ar.c).
  This DLL can be used from VisualBasic, HSP, and other languages, and that seems the only merit.
* A thread-safe version is being developed. 
  Keep in mind that a test is not enough.
* I used MinGW(http://www.mingw.org/) for binary generation.
* I got to know for the first time on this (Mr. Shin-ichi Tsuruta's Japanese) Website(http://www.emit.jp/)
  about Mersenne Twister. I used GCA(G Compression Archiver is developed by Mr. Shin-ichi TSURUTA) regularly.
  I appreciate Mr. Shin-ichi TSURUTA.
* I referred to this Website(Japanese)(http://www.asahi-net.or.jp/~kh4s-smz/spi/note/minispi.html) about
  BCC55(Borland C++ Compiler 5.5).
* I'm thankful to Mr. Makoto Matsumoto(http://www.math.h.kyoto-u.ac.jp/~matumoto/eindex.html),
  who has kindly agreed to this release of MT as a DLL.
