[ANN] Nyacc version 0.83.0 released

[Matt Wette <matt.wette@gmail.com>]

Nyacc version 0.83.0 has been released.   Nyacc is a set of Guile 
modules for generating parsers,
parsing C code, and converting C headers to Guile Scheme.

Version 0.83.0 includes the following changes over version 0.82.4:
1) changes to nyacc/lex.scm to read octal constants
2) change in C99 parser to allow lone `;' in structs and unions
3) fixed but in C99 parser which was truncating long CPP defines
4) change in C99 parser to make get-gcc-inc-dirs more accurate
5) updated C99 pretty printer to handle initializer lists
6) many changes to the ffi-helper

Some FFI Helper changes:
1) many code updates, api changes, etc
2) updates to the documentation (see examples/nyacc/lang/c99/ffi-help.texi)
3) added procedure "load-include-file", which is feature Ludo asked for:
      guile> (load-include-file "cairo.h" #:pkg-config "cairo")
    This will load FFIs for all C declarations in cairo.h into the 
current module.
    Not flushed out.
4) added procedure "fh-cnvt-cdecl" for playing around with the FH.
      guile> (use-modules (nyacc lang c99 ffi-help))
      guile> (use-modules (bytestructures guile))
      guile> (use-modules (system ffi-help-rt))
      guile> (use-modules ((system foreign) #:prefix ffi:))
      guile> (define fh-llibs '())
      guile> (define fexp (fh-cnvt-cdecl "fmod" "double fmod(double 
x,double y);")
      guile> ,pp exp
      $1 = (begin
        (define ~fmod
          (delay (fh-link-proc
                   ffi:double
                   "fmod"
                   (list ffi:double ffi:double)
                   fh-llibs)))
        (define (fmod x y)
          (let ((~x (unwrap~float x)) (~y (unwrap~float y)))
            ((force ~fmod) ~x ~y)))
        (export fmod))
      guile> (eval exp (current-module))
      guile> (fmod 2.3 0.5)
      $2 = 0.2999999999999998


NYACC, for Not Yet Another Compiler Compiler!, is set of guile modules for
generating parsers and lexical analyzers.  It also provides sample parsers
and pretty-printers using SXML trees as an intermediate representation.

NYACC maturity is beta level.
