[ANN] NYACC version 0.91.0 released

[ANN] NYACC version 0.91.0 released

[Matt Wette]

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.

------------------------------------

Changes in this release 0.91.0 compared to 0.90.0 are:
1) added c99 pragma to output tree
2) much work on c99/__attributes__; added support in c99/pprint
3) reworked c99 __asm__, and __builtins
4) cleaned up "-X" argument to guild compile-ffi
5) moved out modelica, this will be a separate project
7) removed old example code: cxx, dxl
8) cleaned updated documentation
9) cleaned up calculator example
10) fix for bug #55527 and #109622
11) reworked configure and Makefiles


My plan for release 0.92 is to update to use autoconf toolset.
