Thanks Ralf for replying. I guess you're right and I will have to use
some checks to configure the library. I'm using libtool for this and
I'm creating a static librar .a. Could you expand on the differences
between static and dynamic libraries? Or forward me a link where I can
see the differences?
Once again, I appreciate your comments.
