ltmain-dunno-yo-lib-make-specific-01.patch

[Guido Draheim]

There are five different places saying
  echo "*** Warning: This library needs some functionality provided by $deplib."
  echo "*** I have the capability to make that library automatically link in 
when"
  echo "*** you link to this library.  But I can only do this if you have a"
  echo "*** shared version of the library, which you do not appear to have."
but each one is provoked by a different check. They should be different.

The following patch changes the first "warning:" line into something 
more specific that points maintainers to the actual kind of check that
failed during execution. Furthermore it adds one or two lines to the
end of this message block explaining things to the user where this
message had been found not quite intelligible in many cases.

Hope this one gets into cvs soon.
