Well that sucks :(
I suggest changing the LT__SETERROR macro in
libltdl/libltdl/lt__private.h to print __FILE__ and __LINE__ etc. if
errorcode == FILE_NOT_FOUND, then running test 71 again. It doesn't
look
like it's happening in loadlibrary.c.
../libtool/libltdl/loaders/preopen.c (188)

Hmm. Adding more debug output to preopen.c:vm_open ...
Searching for preloaded symbol table for dlopen.a
Err...why is it looking for a module named "/usr/bin/last"? Is it
somehow using a $PATH search, and matching "last" to
"/usr/bin/last.exe"? cygwin's dlopen does do some funky things with
$PATH, because that's how windows looks for DLLs -- but we're in
preopen, here...
Ok, it's adding a loader (at the end of the list of loaders), then
trying to lt_dlopen("last"), that's going to try all other loaders
before getting to the added loader, and in your case the loadlibrary
loader finds /usr/bin/last (because /usr/bin is properly in the search
path).
My changes to lt_dlerror should have given you the error from
loadlibrary.c, but didn't, I will check why, it looks like the patch
needs more work though.
That error could just as well come from the last_open function.
I've got this nagging feeling that something clobbers the module
name before it reaches the last_open function and that it's
that clobbering that is the cause of the failure. Not time to
check the details ATM though, sorry. So, I'm still curious about
the output with the patch in the below message applied (on Chucks
setup).
http://lists.gnu.org/archive/html/bug-libtool/2010-06/msg00054.html
Perhaps the presence of /usr/bin/last.exe is triggering that
clobbering. Serious WAG warning...
Cheers,
Peter
