The problem is that libtool is a portable shell script and arguments 
need to be passed to the utilities it executes, with all that that 
entails (e.g. argument splitting and handling of special quote 
characters).  If libtool was a binary, then this problem would be 
gone.

A future issue is that libtool is configured via an autoconf configure 
script which may be a 1MB portable shell script, which also needs to 
survive the torture-test.

Somehow this still usually manages to run under MSYS. :-)
