Part of my wonderings are, no doubt, due to not keeping up on more
recent C standardization or even gcc extentions (as this was) for that
matter.  My primary C reference is still K&R and/or Harbison&Steele.
So, one question might be, what is a currently germane C reference?

Another topical question for me is: what are good tools for exploring
existing code?  Particularly in figuring out the overall structure of
a project.  I am thinking of a call tree (this function calls these
other functions) kind of thing.  Or other similar tools that are
useful, beyond, say, /usr/bin/less.  What do people find useful?
