Re: characters allowed in --enable-*/--with-*

    So gnulib could have --enable-c++.

I guess I missed some discussion on bug-gnulib.  Overall, "cplusplus"
seems like it would have been simpler/more customary.  (That ++ causes
endless hassle everywhere.)

    Easier to remember option names?  Dunno.

I'd say the opposite: allowing lots of "random" characters makes it
harder for users to know/guess/remember option names.  Aside from
technical issues with quoting and the like.  Overall, my thought would
be to allow as few characters as possible.  [-_A-Za-z0-9] and + if we
have to seems perfectly sufficient to me.

Personally I think - should be used in preference to _ wherever possible
in option names, for the reason above: easier for users to remember if
there are fewer variances.

    Sure; later.

Thanks.  Will await :).
