interix 3.5 and shared libraries

[Matthew L Daniel]

My purpose is two-fold: 1. I would like to put this on the radar, since
no mention is made in any of the lists I could find 2. request input on
further steps I should take.

I have verified that gcc on Interix does, in fact, create shared
libraries but I am not sufficiently experienced with either libtool
architecture or m4 to be able to hack in the support for it myself.

Please see below for snippets from the configure script in
libtool-1.5.2.

  Thank you,
