Hello.

As you may know I'm working on the documentation migration from texinfo to Sphinx
and I noticed you have quite some documentation written in Texinfo. Thus, I tried
using my conversion script, but ended with:

$ m2/boot-bin/mc --olang=c++ --h-file-prefix=G -I/home/marxin/Programming/gcc2/gcc/m2/gm2-libs -I/home/marxin/Programming/gcc2/gcc/m2/gm2-compiler -I/home/marxin/Programming/gcc2/gcc/m2/gm2-libiberty -I/home/marxin/Programming/gcc2/gcc/m2/gm2-gcc --quiet  --gcc-config-system --extended-opaque -o=m2/gm2-compiler-boot/M2GCCDeclare.c /home/marxin/Programming/gcc2/gcc/m2/gm2-compiler/M2GCCDeclare.mod
/*  --extended-opaque seen therefore no #include will be used and everything will be declared in full.  */
terminate called after throwing an instance of 'unsigned int'

Have a couple of questions:

1) What's gcc/m2/www/tools/createhtml.py about? Will you need it once the branch is merged to master?
2) You generate some texi files on fly: ./gcc/m2/gm2-ebnf.texi, ./gcc/m2/Builtins.texi
Would it be possible emitting Sphinx in the future?

Thanks,
Martin
