Hmm, issue about -ldl is strange. It looks to me that libtool adds this
link-library. The code in config/tcl.m4 shouldn't be active for windows-host.
Patch for bfd
ChangeLog
2012-02-11 Kai Tietz <kti...@redhat.com>
* configure.in (windows.h, dlfch.h): Add check for headers.
* configure: Regenerated.
* plugin.c: Add for windows-native targets dl-api emulation.
