Re: Darwin and archive_cmds quoting

[Gary V . Vaughan]

Hi Kevin,

It looks like the echo command found by libtool is removing some of the 
backslashes that it is supposed to leave behind.  Here is what it boils down 
to:

  $ echo=echo
  $ foo='`'
  $ quote='s/\([\\"\\`$\\\\]\)/\\\1/g'
  $ double_quote='s/\([\\"\\`\\\\]\)/\\\1/g'
  $ delay='s/\\\\\\\\\\\$/\\\\\\$/g'
  $ eval "bar=\\\"\`\$echo \"\$foo\" | \
    sed -e \"\$double_quote\" -e \"\$quote\" -e \"\$delay\"\`\\\""

And this is what I get:

  $ echo $bar
  "\\\`"

I guess you will get:

  "\\`"

If so, we need to figure out how to find an echo command that doesn't 
interpret backslashes on your machine...  any ideas?

Cheers,
        Gary.
