I used Pelles C for a while, mainly for Windows CE development. Although the IDE was nice, I still preferred LCC-Win32 for Windows development. I have no idea how both environments have progressed in the last 4 years or so.
Check LCC-Win32 here: http://www.cs.virginia.edu/~lcc-win32/
Edit: actually it seems the CCL is still mostly just a bunch of docs. Meh.

I believe they have binaries for Linux as well these days but I haven't tried them yet.
