XSB Src (SVN)-old

Fixed bug in term_size in handling 0-ary function symbols.
(Pointed out by Miguel)

Flag initialization (that I had forgotten)

Restores 'C'/2 which I'd incorrectly commented out (due to compiler warning.)

Add stat_flag and set_stat_flag clauses for erros_with_position flag
(Miguel)

Fixed bug in path get ancestor. (On unix have to stop if get to '/').

Added ability to throw the position of a sytax error in the error-ball.
(by Miguel Calejo)

Added new flag for throwing syntax errors in read with positions. (-Miguel)

Added comments so emacs coloring of .tex files doesn't get confused.

Comment out unused code to eliminate compiler warnings.

Changes in parse.P to allow XSB to serve as an external preprocessor for Prolog
programs.
Added --ignore command-line option to make it possible to ignore the remaning
command-line arguments. Needed to ignore the file name, which is tacked on to
all XSB preprocessors.
Added the 'NOWARN' wrapper to silence the spurious warnings produced by the
conditional compilation code.
Added explanations to the manual to show how to use XSB as a preprocessor.
Some fixes in the curl manual.
