None of this has anything to do with CWEB.  I don't know why Automake is
warning about `:=' style assignments.  I am not that concerned about them
not being portable.  Not portable to what systems?  It is reasonable to
assume the GNU Make is available.  If it works on your system, I'm not
going to worry about it at present.

I can't do anything about this.  It's needed in order to turn off
optimization when compiling `parser.c++'.  `AM_CXXFLAGS' won't work.  I've
discussed this with the Automake maintainers.

I'm quite happy to use GNU make extensions.

Apparently, you don't have the GNU Scientific Library (GSL) or `configure'
isn't finding it.  Check the output of `configure' or your `config.h'
file.    If it's found, the following preprocessor macros should be
defined:

/* Define to 1 if you have the <gsl/gsl_complex.h> header file. */
#define HAVE_GSL_GSL_COMPLEX_H 1

/* Define to 1 if you have the <gsl/gsl_complex_math.h> header file. */
#define HAVE_GSL_GSL_COMPLEX_MATH_H 1

/* Define to 1 if you have the <gsl/gsl_matrix.h> header file. */
#define HAVE_GSL_GSL_MATRIX_H 1

/* Define to 1 if you have the `gsl' library (-lgsl). */
#define HAVE_LIBGSL 1

If it's installed but `configure' isn't finding it, e.g., if it's in an
unusual location, you may have to set the environment variables `CPPFLAGS'
and `LDFLAGS' in your call to `configure'.  This is what I have to do on
my system:

configure --prefix=/home/uni04/UHSK/lfinsto1/3DLDF \
CPPFLAGS="-I/usr/product/parallel/GSL/gsl-1.6/" \
LDFLAGS="-L/usr/product/parallel/GSL/gsl-1.6/lib -lgsl -lgslcblas"

> or you say NO-syntax-highlighting has handicapped me :\

It's up to you if you want to use syntax highlighting.  It's a matter of
personal taste.  I find multiple colors in printed text distracting and I
know the syntax of C and C++ without them.  I'm not recommending that you
not use it.  However, I have no intention of programming it myself.  You
could try using C++ mode for the CWEB files.  I don't know whether the
non-C++ code would confuse it, though.

`complex' is a data member of `class Complex' and therefore of `*this' in
`Complex::show'.  Its type is `gsl_complex', which is declared in the GSL
library.  Since the library isn't being found, this type isn't declared. 
I believe `GSL_REAL' and `GSL_IMAG' are macros, but they might be
functions.  They are also declared (and defined) in the GSL library.
