Num Recipes in C (Index converter or Diffs)

[James Darrell McCauley]

Numerical Recipes in C is a great book (praise, praise, praise),
but, if any of you have ever tried to use their code, I'll bet
you can guess what really ticks me off about it.... It seems
that FORTRAN programmers wrote the C code 'cause all array indices
start at 1 instead of 0 (zero).

I bought the source from Cambridge, but rarely use it because of
the confusion.  Does anyone have
  1) a filter that will "fix" all of the code (this would probably
     be very difficult to write), or
  2) information on diffs, or
  3) information on a newer release of the code distributed by
     the publisher.

While I'm in the question asking mode, does anyone have code to 
find eigenvalues for nonsymetrical matrices that I could distribute
in a program that I'm writing?  I've seen discussions about the
copyright of the code in Num. Recipes but forgot what the general 
conclusion programmers reached concerning incorporating it
in programs that will be made available to the general public.

(distributing other folks libraries with my program is NOT an
 option.  I'm only looking for source in C (!= FORTRAN) that
 I can easily extract (in case your thinking of mentioning
 some big package that won't allow me to do this).

Email only, please. Thanks.
