comments on building emacs-18.55

[Chet Wood]

I just built emacs using the diffs on apple.com-- it has Dave Berry's
name on it:
	emacs-18.55.aux.diffs.Z

I got it built but had to hack things around a little bit. (Guess I'm
spoiled. On the Sun, all you have to do to make gnu things is type
"make.")

The most surprising thing is that, though the symbol AUX is used
liberally in the patches, it is never defined! Things seemed to
compile OK without it-- I only discovered it because I defined
HAVE_X_WINDOWS, so had to change a few things around. Trying to make
my changes dependent on AUX wasn't working, so I checked around
and couldn't find it defined anywhere!

I also ran into the problem someone else mentioned on the net of
clashes between the variable PC in the term*.c and gm.h files, and
the assembler mnemonic for the PC register. Could someone please
explain why this occurs? I haven't used a C compiler in a long time
that would allow such a clash. I saw the term "register prefixes" used
in a posting but I could find no such term in the gcc documentation.

Here are the patches to fix what I found. They can probably be
appended to Dave Berry's patches and applied all at once. I haven't
done extensive testing on the resultant emacs, but it does come up
under X and visit files...
