I found that all hyperlinks except the ones to Cygwin and SF are dead:
- Colin Peters (doesn't exist)
- Colin Peters' GCC website (doesn't exist)
- Jan-Jaan van der Heijden (doesn't exist)
- Mumit Khan (cannot connect, no server)
- Anders Norlander (points to the same http://www.mingw.org/history.shtml\)
- Earnie Boyd (page not found, no more free hosting at FreeYellow.com)
Thanks for your time.
