Ok, I see. New (untested) patch attached.
BTW, I noticed something which looks a bit strange to me. Beginning at
approximately line 2180 of libtool.m4 (from the head CVS branch),
there are a lot of shell variables which are set up. But some of them
are just set to their current value, for instance like this:
[...]
# The host system.
host_alias=$host_alias
host=$host
[...]
# A symbol stripping program
STRIP=$STRIP
# Used to examine libraries when file_magic_cmd begins "file"
MAGIC_CMD=$MAGIC_CMD
# Used on cygwin: DLL creation program.
DLLTOOL="$DLLTOOL"
# Used on cygwin: object dumper.
OBJDUMP="$OBJDUMP"
# Used on cygwin: assembler.
AS="$AS"
[...]
..etc, etc. What is the point in doing this?
Regards,
Morten

This is s heavy :( As I proposed to Pavel, I'm OK with moving this
warning from `syntax' to `obsolete' for 2.50, and move it back to
`syntax' in 2.51 or later.
Probably later :-)
This way, every body is happy. ?
I'm definitely in favor of this change.

It's all part of a big here document that writes the results of the tests run by libtool.m4 to the start of the generated libtool script. For example libtool.m4 contains tests which discover that on the host system, MAGIC_CMD needs to be /usr/bin/file, so it writes the following snippet into the libtool script: # Used to examine libraries when file_magic_cmd begins "file" MAGIC_CMD="/usr/bin/file" And that, in turn is generated by the here document you quoted above.

Autoconf straight out of CVS will complain about "backquotes and
doublequotes should not be backslashed" when expanding the macro code
of _LT_AC_LTCONFIG_HACK libtool.m4.
The problem is that CVS autoconf changes the way backquotes are
interpreted, and issues a warning (even though it works correctly) in
case they're written the way it used to work with autoconf 2.13.
Replacing \` with ' is even worse, because then the shell won't
expand the variable within `', as we want it.
The only way to do it so that it works with both autoconf 2.13 and CVS
autoconf, without triggering the warning in CVS autoconf, is this
(from CVS automake's missing.m4):
am_backtick='`'
AC_MSG_WARN([${am_backtick}$VAR' ...])
