I first heard about PellesC from TheFreeCountry:
http://www.thefreecountry.com/
It's also worth checking out because the site lists various C libraries, sorted by category, that people may find of interest. The site bills itself as a Free Programmer/Webmaster/Security Resource - and so may be quite interesting for geeks generally.
Hi, I know "thefreecountry", that's great! Just for info, Pelles C is also listed here:
http://programmerstools.org/
You can find lots of stuff there too. Hope the link may be useful ;)
Bye.
