libtool under msys bug

[Sam Thursfield]

Hi
I have found this bug in 1.5 and 2.2.4. The problem is $dllsearchpatch
has a preceding :, which confuses Windows and causes the executable
wrapper script to not work, because it sets PATH to something Windows
doesn't understand. If the preceeding : is removed from PATH in the
wrapper script, it locates all of the DLL's fine.

I have attached my patch which fixes the issue, although I am not sure
of its "correctness". I also found a two year old fix here:
https://thomas.apestaart.org/thomas/trac/browser/patches/libtool/dllsearchpath/libtool.dllsearchpath.patch
I have not tested this and to be honest i don't understand how it
works. My patch simply special cases an empty dllsearchpath and in
this case, does not add a preceding colon.

I would also like to say well done for the immense improvement in
execution speed on win32 since libtool 2, I mean it's like ten times
faster to build a libtool-using project now.

Hope this bug report helps.
