SUS does not agree with you
(<http://www.opengroup.org/onlinepubs/007908799/xcu/chap2.html#tag_001_014_0
04>):

. file
 DESCRIPTION
The shell will execute commands from the file in the current environment.
If file does not contain a slash, the shell will use the search path
specified by to find the directory containing file. Unlike normal command
search, however, the file searched for by the dot utility need not be
executable. If no readable file is found, a non-interactive shell will
abort; an interactive shell will write a diagnostic message to standard
error, but this condition will not be considered a syntax error.

My favourite newbie question - "hey, what's this - "foo not found"? I have
it here, right before me, in current directory!" :-)

I guess you are saying that you have a shell that

Autoconf sticks ./ for non-absolute names so it is *not* only my shell; in
generated configure (2.52):

echo "$as_me: loading cache $cache_file" >&6;}
    case $cache_file in
      [\\/]* | ?:[\\/]* ) . $cache_file;;
      *)                      . ./$cache_file;;
    esac

I do not care if ltconfig exists or not - I do care that whatever program is
used for libtool configuration does not break reading config.cache. Anyway I
Cc it to lftp list, they may be interested in using newer version.
