This error is occuring in the libltdl code which is placed in the Hamlib
tree by the autogen.sh bootstrap process.  As this code came from your
Libtool installation, I'm afraid that I'm in the dark as to the reason.

I suspect it is more of a MinGW issue than Autotools.  As there are
intentions to remove the need for libltdl at some point in the future,
this issue may resolve itself at some point.  ;-)
