That is why only static libs are created by default.
You _have_ to use --enable-shared to get dynamic ones.
I think that we should be able to use libtool always without problems.
(and if we get problems, static libs for any given arch should be
quite easy to add)
Also, I am not going to work on making shared work on other archs
than ix86/Linux (and that already work). We will slowly move to have
better module/library api's and dependencies but do not expect much.
btw. did you try --enable-shared on OS/2? How severly did it bomb?
