installed when libtoolize finishes, but with others it is not installed
until automake has finished.

So we can not attempt to use config.guess until the very last buildconf stage.

  is almost always a VERY BAD IDEA. Yet there are still apps out there doing
  this, and now recently it triggered a bug/side-effect in libcurl as when
  libcurl sends a POST or PUT with NTLM, it sends an empty post first when it

Yet unknown error might leave libtool-like files in source directory.

This can be done now that no file with such name exists in CVS tree.

what the best way is to provide one.
