I see, that's good to hear.

Okay, but there's something amiss, just compare a local gcc.info with 
that.  The sphinx generated one seems to only contain command line 
options, but none of the other topics, in particular it seems to contain 
the "Invoking GCC" chapter (and only that) as top-level, and all other 
ones are missing (like "C implementation", "C++ implementation", "C 
extension", and so on).

Looking at gccint.info I also seem quite some confusion, it's unclear to 
me if content is missing or not.  But e.g. the top-level structure has a 
different order (a less logical one, this one is btw. shared with the 
order of the HTML generated docu, so it's probably specific to sphinx 
setup or such).

Ignoring that missing content what is there right now does seem somewhat 
acceptable for local use, though.


Ciao,
Michael.
