Patch for sC++ to GNU C++.

[Jan Madsen <Jan dot Madsen at epfl dot ch>]

Hello,

I have previously worked with Mike Stump concerning the insertion of
this patch (first time 3 years ago). In August I contanted Jason
(jason@cygnus.com) but I have never got any answer, Mike Stump has
therefore suggested me to contact you in order to get this patch into
egcs.

The patch allows the GNU C++ compiler to accept a small concurrent
extension called sC++ (home page: http://ltiwww.epfl.ch/sCxx). The sC++
extension adds 6 new keywords to the C++ language, they are however only
reserved if the source file to be compiled have one of the extensions
'.scxx' or '.scc' (or the flag '-fsyncc++' is used). Otherwise this
extension does not change the behaviour of the C++ compiler frontend.
Below you find a suggestion for a changelog entry for this change.

        Insertion of the sC++ language extension.
        * Makefile.in: Added rules for sc*.c files.

        * decl2.c: Added flag 'syncc++' to list of flags, and variable
         'flag_synccxx'.

        * gxx.gperf: Added reserved words for sC++, regeneration of
hash.h
          required.

        * lang-options.h: Added flag '-fsyncc++'.

        * lang-specs.h: Added part for sC++ extensions ('.scxx' and
'.scc') and
          specs part for these extensions.

        *lex.c (init_lex): Unset sC++ specific keywords if extension not
used.

        *parse.y: Inserted actions and rules for the sC++ extension
(embedded
         in an 'if (flag_synccxx)').

        *sc-accep.c, sc-activ.c, sc-body.c, sc-const.c, sc-defau.c,
sc-destr.c,
         sc-foral.c, sc-meth.c, sc-misc.c, sc-names.h, sc-selec.c,
sc-selec.h,
         sc-setre.c, sc-stack.c, sc-wait.c, sc-when.c, sc.c, sc.h: New
files. 


You may obtain the complete patch (60-100kb) at the address (or I can
send it to you upon request): 

          http://ltiwww.epfl.ch/~madsen/gnu.html

I have put up two different versions of the patch: one with and one
without the kernel realising the concurrency in sC++. Each patch
decompress into a directory called sc-diff. We have already assigned the
copyright for the patch and the kernel to FSF.


Regards,

Jan Madsen

PS. Please let me know if I can do anything in order to facilitate the
    integration of this patch.
