I'm confused by this response.  The shared library is an exe that gets auto
loaded by the system and is shared by multiple processes.  The contents of
the .a files get bound to your program and become part of the exe
(and never the twain will meet).  Binding with the shared library requires
linking with the shlib.ifile which gives the entry points into the shared
library to the linker so that it can resolve references.  If the shlib.ifile
came with the OS and the shlib exe came with the Utilities (or vice versa)
then you would have a problem.  Whether the .a files and the shlib are of the
same release should be irrelevent.  What are you trying to say?
