[ANN] nyacc 3.02.0 released

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.

It provides a decent C parser and a `FFI Helper' tool to help create
Guile Scheme bindings for C-based libraries.

It provides (partially implemented) compilers based on above mentioned
parsers to allow execution with Guile as extension languages.

Updates for 3.02.0 from 3.01.1
         * Many thanks to #lechner for persistence in testing new commits!
         * Updated ffi-helper to allow other backends (e.g, bstruct,
           bytestructures).  See github.com/mwette/guile-fhbe. This was
           accomplished by adding a layer of indirection for low-level
           type construction.
           + Compile time for gtk2.ffi is 5% longer.
           + Compiled ffi modules include case-backend syntax form.
             (See ffi/cairo.ffi for an example use case.)
         * Moved ffi-help-cd.scm back to ffi-help.cd, like for v1.0.
         * In cdata, removed support for previously deprecated types (e.g.,
           "signed long int") in preference for canonical short names (e.g.,
           "long"), as parse-c99 does not produce them.
         * Merged "powerpc64le" machine arch (from #gwitmond) into 
arch-info.
         * Added s390x machine arch (thanks #rlb) into arch-info. issue#27
         * In cdata, exposed procedure make-cdata/* which will create
           an object from a pointer.
         * The cdata user guide has been reviewed and expanded.
         * cdata-ref now returns scheme array and struct values as Guile
           objects (array and alist).  To get cdata objects, use cdata-sel.
         * cdata-set! now accepts scheme arrays (and vectors) for carray and
           alists for cstructs and cunions.
         * Fixes issue#22: buggy cdata-ref/set! with anonymous 
struct/unions.
         * Fixes issue#24: c99 parsing empty-structs (struct { };).
         * Fixes issue#25: attribute arguments w/ math expressions.
         * Fixes issue#26: __u32 not found => major bug in process-decls 
0cc90f6
         * Fixes issue#49: use asm-based link name for foreign-pointers
         * Worked more on the "mlang" language example parser and analyzer.
         * In define-ffi-module identifier ffi-arch is available march.
