[Autoconf] Re: HTML format documentation

[Richard Stallman]

    XEmacs already uses --with-cc and --with-cflags, although I'd tend to go
    for the shorter --cc=sun-cc and --cflags=-O2.  You'd also need --cxx and
    --cxx-flags; I'm not sure what other environment variables are similarly
    special.

If we go in that direction, should we say that ALL the standard Make
variables should have configure options?
