        This is just a minor problem, you may not have seen before if
you're used to windows or other non-gnu compilers.  It just means that
somewhere, you didn't close your double quotes.

        For example,

int function_x(int x) {

  printf("I got %d\n",x);
  printf("I will error because of this line);

  return x;

        See? simple.  Though, it may tell you the line where the error is
is actually on that last closing brace - or the end of the file.  You just
have to know what it means and what to look for.

        Well, you can also run gdb on an active process (or run an active
process with gdb!).  If you're looking for a pre-compile checker, there
are quite a few out there dependant upon your OS.  I prefer lclint, which
is a free linux lint-clone (lint is a commercial product for mainly SunOS
which does checking).  There are others, but I don't think you need that
level of checking, as they do things like bounds checking, style/syntax,
variables/function definition, etc.  I think lclint gets about 40-50 lines
into the circle code before it craps out with 'too many errors' (about 300
lines or so of problems).  It's kinda picky.

        I suggest you just open up another screen while you're editing,
and any time you make changes and get a compile-time error, look at the
code before you changed it, and see what you're doing differently.  You'll
get used to which errors make which problems soon enough.
