It needs to be done in libltdl/config/ltmain.m4sh.

The trailing ? after pe-x86-64 is wrong, pleasse drop it.

Can you be bothered to check out the Libtool git tree or a nightly
snapshot (see homepage for links) and, with above change, build it
and run the testsuite on win64, please?  We'd be interested in any
failures of
  make -k check

(add VERBOSE=yes for verbose output of the old testsuite, and send
tests/testsuite.log for failure of the new one).

You'd need Autoconf for rebuilding Libtool, and also Automake for
running all tests.

Thanks!
Ralf
