I would strongly recommend using '--std=3Dc99' (or as necessary
'--std=3Dc89') to compile older code with a newer compiler such as GCC-14.

It also wouldn't be wrong to add '-fpermissive' as well.

The code was written to an older standard so don't try to foist new
language features on it without very careful consideration!

You really don't have to fix innocuous warnings just because the
compiler now defaults to a newer language standard that's not entirely
backwards compatible.

Of course real bugs should be fixed and reported.

Note too that Lout's makefile has long specified '-ansi', which is of
course equivalent to '--std=3Dc89', along with '-pedantic'.

That said perhaps you haven't noticed the latest release from June of
last year that fixes all warnings (though I've found it needs to be
adjusted to use '--std=3Dc99' instead of '-ansi'):

     http://jeffreykingston.id.au/lout/
     http://jeffreykingston.id.au/lout/lout-3.41.tar.gz

nThere's also William Bader's work to clean up warnings and make some
fixes:

I would like to see him rebase any of his changes still "necessary" onto
Jeff's 3.41 though before recommending it wholeheartedly.
