looking for online howtos/tutorials for newbie developers

["Robert P. J. Day" <rpjday mindspring com>]

  i'm interested in collecting some online tutorials that cover introductory
development using gcc.  things like basic gcc, simple options, how libraries
work (dynamic versus static linking).  in a more general sense, also, 
overviews of the entire GNU set of development tools.

  i'm aware of o'reilly's book "programming with gnu software", which 
would probably be ideal if it weren't several years old.

  and, of course, all of this to be done under linux.  thanks.
