[PATCH] Quote 'like this', not `like this'.

[Paul Eggert]

In 2012 the GNU Coding Standards changed to recommend quoting
'like this' or "like this" instead of `like this'.
Alter diagnostics and comments accordingly.
Use a more-consistent quoting style in config.sub diagnostics,
preferring 'like this' to "like this" as the former is more
resistant to shell metacharacters.

I am a bit disenheartened to see that Ben hasn't sent any email to this 
list since he installed the change in question, back in November. If 
he's retired (which I hope not), we'll need to find a new maintainer 
whose lap we can dump this problem into. I'll cc this email to him to 
give him a heads-up about the thread.



1) There is no actual benefit to using $(...) over `...`.


I disagree with that statement on technical grounds (not merely cosmetic 
grounds), as I've run into real problems in using `...` along with " and 
\, problems that I would not have run into with $(...). The Autoconf 
manual describes some of these problems.[1]



Talking about # as an analogy is a red herring. # does not cause
real-life problem.


# caused a real-life problem for me on a real-life system, around 1979. 
Of course the problem set has changed since then, but the compatibility 
principle hasn't.

I prefer to draw the line at systems that are no longer supported by 
their own suppliers. For Solaris, that means I worry only about Solaris 
10 and later, as Oracle no longer supports older versions.


However, this is not a boundary formally set by the GNU project, and 
different developers can choose different boundaries, as described in 
"Platforms to Support" section of the GNU software maintainers manual 
.


config.sub/config.guess are special in that they're shared among so many 
projects, and so the boundary that Ben uses affects a lot of projects' 
configuration code.

The only rationale provided by the previous maintainer so far is a short
message in config-patches mailing list [1].


The config maintainer Ben Elliston has wanted to get rid of the 
old-fashioned accent graves for many years. In November 2017 he 
installed a change to do that, but I explained it wouldn't work well on 
Solaris 10 so he reverted. Two years ago he asked me about this again, 
and I responded that Solaris 10's end-of-life was scheduled to be 
January 2021 and so it'd be best to wait until then, and he agreed. Last 
April we emailed each other again about this, and I told him that Oracle 
had extended Solaris 10's end-of-life to January 2024 but he demurred, 
writing that he didn't want to wait the extra three years.


Except maybe for Solaris 10, shells that don't grok $(...) are museum 
pieces now. And anybody on Solaris 10 (which occasionally includes me, 
as my department still uses Solaris 10 on some machines) can easily run 
a better shell like /bin/ksh. It's a bit of a maintenance hassle for Ben 
to deal with `...` (it doesn't nest, and it has weird rules when 
combined with "...") and it's understandable that he would rather deal 
with actual config.guess problems than with completely-obsolete shells 
that don't support standard syntax.


I recall having a similar discussion back in the 1970s, when a shell 
script stopped working for me because its author put in a comment 
starting with "#", something the 7th Edition shell did not support. I 
wrote the author, who suggested I get a better shell, and life went on. 
And I'd expect a similar reaction today if someone asked us to remove 
the "#" comments from config.guess on the grounds that they don't work 
with Steve Bourne's original V7 shell.


At some point, failing to support $(...) is in the same ballpark as 
failing to support "#". I can see Ben's point of view that we've reached 
that point even if I would have waited another three years, so if Ben 
would rather use $(...) I'd rather not overrule him downstream.

A gawk user recently called my attention to:

https://github.com/msys2/MSYS2-packages/tree/master/gawk


The patch file there is named gawk-4.2.1-msysize.patch.  The patches mainly
seem to add an "msys*" option in several build scripts just after the
"cygwin*" system identity alternatives.


I have adapted the patches for gawk's test/Makefile.am and will be
pushing shortly.

Can we get the changes for compile, config.guess, config.rpath, and
ar-lib integrated directly into GNULIB, so that I can then pull them
from upstream?


I installed most of those changes to Gnulib. The exception is the proposed 
change to config.guess, which is upstream from Gnulib and is part of GNU config, 
so I'll CC: this message to config-patches@gnu.org.


As far as I can see, the proposed config.guess change has no effect, as the 
existing config.guess treats MSYS the same on all architectures in an earlier 
branch of that big 'case' statement. config.guess has done so since this commit 
in 2014, which specifically caused config.guess to treat MSYS the same on all 
machines, not just i* machines:


https://git.savannah.gnu.org/cgit/config.git/commit/?id=f4ebd3ed097771a729b68e688236aea665e7c1f3

so I'm puzzled as to why the config.guess change would be needed even if it were 
effective.

${parameter:-word} is in POSIX, but I don't know how portable it is to

Although it does not work on old Bourne shells, I suspect we don't need 
to worry about them any more.


The "Shellology" section of the Autoconf manual says ${VAR:-VALUE} 
causes old BSD shells to complain and die, and mentions Ultrix. However, 
as far as I know these old shells are now museum pieces. The last Ultrix 
release was in 1995. I haven't fielded an Ultrix bug report for many years.


For what it's worth, 'configure' scripts are still portable to Ultrix 
because they search for a POSIX-compatible shell by trying a list of 
programs that includes 'sh5', which was how Ultrix did it. I think this 
was due to the late Fred Canter, who specialized in getting the farkles 
out.  See:
