From a command line, I get this:
$ echo "foo\\bar\\baz" | tr -d '\'
tr: warning: an unescaped backslash at end of string is not portable
foobarbaz
$ echo "foo\\bar\\baz" | tr -d '\\'
foobarbaz
My guess is that procmail is eating one level of the backslashing, so
it's passed to tr the way it is in my first example, generating the
warning.
If this is correct, you could fix it by changing the line to:
# procmail removes one level of \-escaping, so pass \\\\ to get \\
TMPVAR7a=`echo "${TMPVAR7a}" |tr -d '\\\\' ; :`
